The Complete Guide To Unlawful Carnal Knowledge: Sexualis Morbus (Sexual Diseases)

You are visitor number 1493 since August 2006.

SEXUALIS MORBUS (SEXUAL DISEASES)

This system does not attempt a specific treatment of a subject which is beyond its scope and purpose. What is done, however, is to give general categories of disease and maladies and their game effects.

Chance Of Contracting A Disease

To contract a sexual disease, the character must be having sex with somebody who already is inflicted with a disease. The base chance for contracting a natural disease is 1% per round of sexual activity. The base chance for contracting a magical disease is 2% per round of sexual activity. Modifiers are as followed:

Constitution of character
1-3 +4 13-15 -2
4-6 +2 16-18 -4

Constitution of character
1-3	+4	13-15	-2
4-6	+2	16-18	-4

     Constitution of character
      1-3    +4     13-15  -2
      4-6    +2     16-18  -4

protected intercourse / 2 (cuts the chance in half)
unprotected intercourse X 2 (doubles the chance)

Thus, Rath (con. 14) becomes intimate with a person that has a natural sexual disease unfortunately he prefers not to use protection (like a sheep-skin condom). He participates in 18 rounds of sex. His chance of getting a disease is 32% (18-2 X 2). He rolls a 28 on the percentile dice. Thus, our hero now is infected with a sexual disease. If only he used protection, his chance of contracting a disease would have been a mere 8%. A lesson to be learned.

The use of Protection From Disease and Cure Disease spells are of course very useful for preventing and curing disease.

Random Determination Of Who Is Diseased

The GM should decide of the person a character has sex with is infested with a disease, but if he wants to decide randomly, this system is provided. The chance of a prostitute having a disease is already established if Getting To Know A Prostitute (Random Generator) section of the guide is used. Therefore, the system is provided for non-prostitute people. Also, this system doesn't handle whether diseases are natural or magical because some GM's may have magically rich campaigns ands others may not so odds may vary.

The base chance of having a disease is depend on the size of the settlement (the theory is that more diseases are found in bigger settlements where more people interrelate):

Thorp, Dorf 10
Hamlet 25
Village, Wych 30
Town 35
City 40

Thorp, Dorf	10
Hamlet	25
Village, Wych	30
Town	35
City	40

     Thorp, Dorf     10
     Hamlet          25
     Village, Wych   30
     Town            35
     City            40

Modifiers to the base chance are by social level (the theory is that more disease are transmitted amongst the lower classes because there are dirtier and less careful):

Lower Lower Class +20
Middle Lower Class +15
Upper Lower Class +10
Lower Middle Class +5
Middle Middle Class 0
Upper Middle Class -5
Lower Upper Class -10
Middle Upper Class -15
Upper Upper Class -20

Lower Lower Class	+20
Middle Lower Class	+15
Upper Lower Class	+10
Lower Middle Class	+5
Middle Middle Class	0
Upper Middle Class	-5
Lower Upper Class	-10
Middle Upper Class	-15
Upper Upper Class	-20

NOTE: not all settlements have these many variations of social level. The GM should be aware of what social levels are around.

     Lower Lower Class   +20                 NOTE: not all settlements
     Middle Lower Class  +15                 have these many variations
     Upper Lower Class   +10                 of social level. The GM
     Lower Middle Class   +5                 should be aware of what
     Middle Middle Class   0                 social levels are around. 
     Upper Middle Class   -5
     Lower Upper Class   -10
     Middle Upper Class  -15
     Upper Upper Class   -20

Thus, a lower lower class citizen of a city would have a 60% chance of having a disease maybe because she sleeps around to get extra food money. In a near by hamlet, an upper upper class citizen would have a 5% chance maybe because he has a private mistress to engage in sexual activity when he is up to it. While in the city, a citizen of equal status has a 20% chance maybe because he parties a lot with the rich and he screws just as much.

At first glance at this system, a person might assume that in a city 9,000 roughly 40% (3,600) of the population are sexually diseased. The first item to note is that this system includes only those that ENGAGE in sexual activity. This eliminates a large amount of the city including children, elderly, etc.. We'll say that half the city engages in sexual activity, which seems like a lot. Social level is another important aspect that must be included. Thus in this example, let us assume that all social levels exist and there population is equal:

                           Total   Sexual   Chance    Total Of
     Social Level          Pop.    Active   Of Dis.   Diseased
     Lower Lower Class     1,000    500   *   60%   =   300
     Middle Lower Class    1,000    500   *   55%   =   275
     Upper Lower Class     1,000    500   *   50%   =   250
     Lower Middle Class    1,000    500   *   45%   =   225
     Middle Middle Class   1,000    500   *   40%   =   200
     Upper Middle Class    1,000    500   *   35%   =   175
     Lower Upper Class     1,000    500   *   30%   =   150
     Middle Upper Class    1,000    500   *   25%   =   125
     Upper Upper Class     1,000    500   *   20%   =   100
                                                       -----
                                                       1800

Thus, 1,800 people of 4,500 people who have sex of 9,000 people that live in the city are infected with a sexual disease. This is a lot, but we're assuming that those that participate in sexual activity do this with more than one person. The thing to keep in mind is that this system is to calculate individual persons, not mass population. When the dice starts rolling, the results usually don't go with the odds.

Natural

Natural sexual diseases might not seem as bad as magical, but they are as terrible. After choosing the desired disease on Table 1, the GM should roll 1d8 to decide occurrence and 1d8 to decide the severity of the disease.

Occurrence determines whether the disease is a single (acute) attack or whether the disease will recur periodically once contracted (chronic). Chronic maladies will affect the character periodically, if they occur at the same time as any other malady (disease, disorder, or parasitic infestation), the severity of both will be increased. Thus, if two chronic maladies are contracted, the character is not likely to survive another disease attack.

Severity refers to the seriousness of the disease, disorder, or parasitic infestation and determines the period of disability (recover time or length of illness which terminates in the character's demise) and the effects of the malady.

MILD:: During the period of affliction the character is unable to perform strenuous activities. Roll once on Table 2 for additional effects. Some treatment may be determined by the GM to allow a shortening of the period of illness. A normal period is 1-3 weeks.
SEVERE:: A severe malady will lower the character's hit points to 50% of normal and make him/her totally disabled for 1-2 weeks, plus a further 1-2 weeks of time during which the malady is in the mild state as the character recovers. Roll twice on Table 2 for additional effects.
TERMINAL:: The malady will cause death (or loss of the body part or function) in 1-12 days (longer periods are stated hereafter in the discussion of the various maladies). Roll thrice on Table 2 for additional effects.

Die Roll	Effect
1	Burning during urination

Description

Enlarged Scrotum Syndrome (E.S.S.)

This disease is only contracted in males. The effect is that the male's testicles become quite enlarged (max. of two feet in diameter each). The victim's movement is quartered. Constitution is halved. The pain is awful and its really embarrassing to be seen. There is a 15% chance each month that chronic victims experience the disease again.

Gonorrhea

An infectious disease of the genitourinary tract, rectum, and cervix, caused by the gonococcus, transmitted by sexual intercourse, and characterized by acute purulent urethritis with dysuria (Hey, its from Webster's Dictionary). There is a 50% chance each month that chronic victims experience the disease again.

Insania

This disease causes the inflicted to gain a sexual insanity disorder (GM's choice; see below). The period of affliction lasts 4d6 months. There is a 10% chance each month that chronic victims experience the disease again.

Prurire

The Itch" as it is better known is quite an uncomfortable but not lethal experience. The period of affliction is 1d4 weeks. There is a 50% chance each month that chronic victims experience the disease again.

Segmen Neus

This disease is named after a disgusting perverse ogre who was always pestering female species. The effects of the disease are as followed:

2 to comeliness each day (gradual disfigurement)
1 to intelligence each day (gradual stupidity)
right leg goes bad making movement decrease by 90%
unable to participate in any sexual activity

There is a 75% chance each month that chronic victims experience the disease again.

Syphilis

A chronic infectious venereal disease caused by a spirochete (Webster's Dictionary is so laborious). There is a 50% chance each month that chronic victims experience the disease again.

Tuna

This disease only manifests itself in female characters. It causes the victim to reek of the smell of fish. Going unnoticed is quite impossible. In fact, if cats are around they will follow the victim. There is a 50% chance each month that chronic victims experience the disease again.

Magical

It is unknown how these magical diseases came about. Some sages say they're from war, some say that a rip in magical fields caused them, others say that creatures having sex with certain magical beings cause weird things. Whatever the reason, magical diseases aren't pretty. Magical diseases don't have an occurrence or severity. They last until dispelled by cure disease, wish, etc.. The GM can pick or roll (2d8) on Table 3.

Some may feel that the these diseases cause to much damage. A first level character can have sex with somebody infected with acid secretion and most likely be killed during the encounter. This is true, but the important thing to remember is that these diseases are magical and are not necessarily that common in society.

Description

Acidic Secretion

The sexual partner receives 2d8 points of damage on any round (GM's choice) during each sexual encounter.

Bitchy Magical Syndrome (B.M.S.)

This magical disease only affects females. Males should reroll on the magical disease table. Females with this disease suffer the effects of The Bitch Rule.

Fiery Secretion

The sexual partner receives 2d6 points of damage on any round (GM's choice) during each sexual encounter.

Mummy Crotch Rot

This disease is fatal in 1-6 months. For each month the rot progresses, the victim permanently loses two points of charisma. The disease can be cured only with a cure disease spell. Cure wounds and regenerate spells have no effect on a person inflicted with mummy crotch rot.

Orgasmatic Monster Summoning

Within one round of an orgasm, summoned monsters appear. There are seven stages of this disease. Each stage is relative to the number of months the inflicted has had the disease. Thus in the first month, the disease would be in the first stage. In the first stage, 2d4 1st-level monsters appear (selected by the GM, from encounter tables). In the second stage, 1d6 2nd-level monsters appear. In the third stage, 1d4 3rd-level monsters appear. In the forth stage, 1d3 4th-level monsters appear. In the fifth stage, 1d2 5th-level monsters appear. In the sixth stage, 1d3 6th-level monsters appear. In the seventh stage, 1d2 7th-level monsters appear. The disease becomes terminal after the 7th stage. The summoned creatures attack whomever happens to be there for a number of rounds equal to the stage number + 10.

Orgasmatic Flight

Upon an orgasm, the inflicted levitates if able (not tied down, etc). Then, he/she takes off in a random direction for 1d20 rounds. Upon coming into contact with a solid object (ex. wall), he/she takes off in another random direction. The GM may assign damage if necessary.

Orgasmatic Polymorph

Upon an orgasm, the inflicted polymorphs into another creature, save those that are noncoporeal, from as small as wren to as large as a hippopotamus. Furthermore the victim gains its physical mode of locomotion and breathing as well. No system shock is required. This affect does not give the new form's other abilities, nor does it run the risk of changing personality and mentality. The duration of the polymorph is 1 turn per constitution point.

Poison Secretion

The sexual partner receives damage (save vs. poison) on any round (GM's choice) during each sexual encounter . Roll (1d20) on the following table to decide damage:

Sexual Audible Glamer

Any time the inflicted engages in sexual activity, he/she has uncontrollable desires to yell, scream, etc. This yell becomes louder as the sexual encounter continues. The volume is based upon the round of sex. During the second round, the volume is that of one person. The ratio is two rounds for one person's volume. Thus, the noise increase to the equivalent of two men during the forth round, the noise of three men during the sixth, and so on.

Sexual Chill Touch

On the tenth round of a sexual encounter, the inflicted causes a chill touch to his/her partner. The partner will take 1d10 points of damage due to the absolute cold. Further, the victim must save vs. paralysis or be utterly unable to move. This paralysis lasts until dispelled in some manner. (This could be real embarrassing to a government official paralyzed in a sleazy establishment.)

Sexual Clairvoyance

The inflicted sees in his/her mind some unknown locale (chosen by the GM) at random times throughout a sexual encounter.

Sexual Invisibility

The inflicted slowly turns invisible when having sex. This transformation begins on the second round and will end when the sexual encounter is finished. At this point, the inflicted will be totally invisible. The duration of invisibility is equal to the amount of rounds of the sexual encounter. (This could be beneficial when a quick an discreet exit is required.)

Sexually Transmitted Lycanthrope

A person with this disease either becomes inflicted with lycanthrope or becomes a carrier of the dreaded disease. The chances to get the disease are as followed:

50% - constitution - 5 becoming inflicted
50% + constitution - 5 becoming a carrier
10% neither

50% - constitution - 5	becoming inflicted
50% + constitution - 5	becoming a carrier
10%	neither

     50% - constitution - 5        becoming inflicted
     50% + constitution - 5        becoming a carrier
     10%                           neither

The type of lycanthrope can be rolled (1d6) on the following table:

1 Werebear 4 Wearboar
2 Werefox 5 Wererat
3 Werewolf 6 Weretiger

1	Werebear	4	Wearboar
2	Werefox	5	Wererat
3	Werewolf	6	Weretiger

     1    Werebear         4  Wearboar
