Sexual Encounters (Game Mechanic)

A rule system for used with Pathfinder 1st Edition intended to allow sexual events to be played out instead of simply being written. It is a modified version of the standard combat mechanics of the game and introduces a number of new rules and elements to character creation. This is an optional system not appropriate for all games or groups but is intended to make erotic events more mechanically engaging for those willing to use it, turning them into a game in their own right.
=Core Concept - Sex as a Game=
The basic idea at work behind this optional subsystem is to make the act of sex in the game into a sort of intuitive minigame that's fun to play and mechanically rewarding, incentivizing Players to approach sex as just another part of the game and not as something to be shoved into the background. I hope that it can make sex in the tabletop form of the Wayfarer's Guide entertaining, a source of humor and excitement. And not just in the sexual sense. I consider this to be important to the setting itself, considering the generally sex-positive attitude the setting has, and especially in dealing with Monsters.
I feel that sex in this world should be fun rather than tedious, especially when you're playing a game in it.
=New Concepts=
In approaching the concept of sex as a game, I found it difficult not to have to resort to at least a few new concepts. Some of these were inspired by erotic video games such as Corruption of Champions and Monster Girl Dreams. Others were inspired by existing mechanics within Pathfinder and Dungeons & Dragons.
==Lust and Libido (LBD)==
===New Ability Score - Libido===
Libido measures sex drive, enthusiasm, viability, and performance. This ability is important for characters who expect to spend significant time romancing or seducing others, such as Tempters, Courtesans, Amalus, Eroticists, Hetaeras, Imagists, Masters, Kundalas, Paramours, and Tantrists. Libido determines the maximum number of times a character may climax before they risk exhaustion. It also affects the rate at which you gain Lust.
You apply your character's Libido modifier to:
* Perform (Sex Acts) unless you are Trained in that Skill and wish to use a different Ability.
* Attack and Damage rolls with weapons that deal Erotic damage.
* Libido Checks (such as to become erect or wet, to gain Lust, 
Your Libido score modifies your Fertility and/or Virility.
Temporary Bonuses: Temporary increases to your Libido score give you a bonus on Libido-based Skill Checks, Erotic Attack and Damage rolls, The bonus applies to your CMB and CMD when used in sex. They also increase the number of times your character may orgasm before risking exhaustion, as well as improving the character's fertility and virility, where applicable.
Permanent Bonuses: Ability bonuses with a duration greater than 1 day actually increase the relevant ability score for 24 hours. Modify all skills and statistics as appropriate. This might cause you to gain skill points, hit points, and other bonuses. These bonuses should be noted separately in case they are removed.
Ability Damage: Damage to your Libido score causes you to take penalties Libido-based skill checks, Erotic attack and damage rolls, and Fertility/Virility. This penalty applies to your CMB and CMD during Sexual Encounters.
Determining Libido: Unlike other Ability Scores, Libido need not always be determined through dice rolls or point buy methods. In fact, it's arguably best in the latter case to generate it by averaging the character's other ability scores. Specifically, average their Strength, Dexterity, Constitution, Intelligence, and Charisma, leaving out their Wisdom, and rounding up to the nearest whole number.
===New Resource - Lust===
A new resource generated over time by a character's Libido, Lust allows represents the character's accumulated sexual urges. As time goes on and they're exposed to sexually stimulating experiences and events, Lust naturally accrues. If left unchecked, it will slowly erode the character's mental and emotional state, and eventually their physical health as well. However, it can also be expended through sex, masturbation, or other methods of release. Doing so alleviates these negative conditions and can have positive effects for your character. Lust can also be used to power special abilities such as Spells, Powers, Maneuvers, and the like so long as they are being used sexually, acting like a kind of emotional inspiration that can serve as a stand-in for Mana Points.
==Arousal - Erotic Damage, Edging, and Climax==
Erotic Damage, or Arousal, represents sexual stimulation that brings a character closer to orgasm. This is normally dealt with the Skill Perform (Sex Act) or through the special combat rules described below. However, just as one can take damage from traps and other environmental hazards, it is also possible to gain Arousal through other methods.
Arousal functions similar to nonlethal damage; it is not "real" damage and does not subtract from the character's current total of HP. Unlike nonlethal damage, a character does not lose consciousness upon having their HP depleted by Arousal. Instead, they orgasm. When a character's total Arousal equals their current Hit Points, they are treated as if they were Disabled, but are considered to be Edging. In this state further sexual stimulation operates in a manner similar to the Dying condition in that additional actions beyond a simple Move cause the character to automatically begin taking 1 point of Arousal per Round until they reach 0 Hit Points, at which point they Climax.
==Sex Traits==
===Sex===
The character's biological sex.
===Gender===
The character's gender identity, usually the same as their Sex.
===Orientation===
The Sex of the character's preferred mates.
===Preferences===
A laundry list of sexual likes and dislikes.
====Turn-Ons and Turn-Offs====
Turn-Ons are qualities the character desires in a potential mate. These reflect simple preferences, providing a slight increase in the amount of Arousal you take from characters that have your characters desirable traits. A character takes an additional point of Arousal per Turn-On that their partner matches, per action. Meanwhile, Turn-Offs represent the opposite; they are undesirable traits in potential sex partners. Instead of causing the character to take more Arousal from sex acts caused by their partner, they reduce the Arousal received by the same amount.
Characters may have any number of Turn-Ons and Turn-Offs. These also serve as a way for Players to signal to their GMs what sort of sex partners they want for their character and what they don't. Turn-Ons cannot also be Turn-Offs, and vice versa.
====Kinks====
Sexual activities, play, situations, scenarios, events, qualities, and the like that the character particularly desires or enjoys. These are more intense than mere Turn-Ons, penalizing their Will Saves by 1 per Kink that their sex partner fulfills. A character can have any number of Kinks, but they must be drawn from their list of Turn-Ons and cannot be a Turn-Off. 
====Fetishes====
Fetishes represent something more intense than simply a Kink.
===Performance===
====Appeal====
====Endowments====
====Techniques====
====Game====
====Style====
Style Sex Traits are based primarily on one's Ability Scores and reflect different approaches to sex. In essence, they're a way of saying that your character's mental and physical capabilities partially dictate how they perform in bed and what activities, positions, and techniques they're best at... and which could use some work.
=====Forceful (STR)=====
=====Steady (CON)=====
=====Dexterous (DEX)=====
=====Knowledgeable (INT)=====
=====Intuitive (WIS)=====
=====Sensual (CHA)=====
=====Enthusiastic (LBD)=====
=== Afterglow ===
Special benefits the character receives from a Sexual Encounter in which they orgasm.
==Viability - Fertility, Virility, and Pregnancy==
==New Conditions==
=== Horny ===
The character's mind is clouded with lustful thoughts, making it difficult to concentrate. 
=== Frustrated ===
The character is filled with sexual desire, finding it difficult to concentrate or gain proper rest.
=== Aroused ===
The character is sexually excited and capable of having sex without penalty.
=== Rut ===
The character is consumed by an intense desire to breed that makes it impossible to concentrate and threatens to override their reason and self-control. Rest is unattainable. Rut represents a situation in which the character's reproductive instincts have become overwhelming, such as during certain species' mating seasons, as a result of powerful aphrodisiacs, magic, or extreme levels of Lust. 
=== Edging ===
The character is on the cusp of orgasm, yet not quite there. 
=== Ecstatic ===
The character is in the throes of orgasm, rendering them incapable of taking other actions.
=== Insatiable ===
The character is incapable of decreasing Lust through sexual activity. 
=== Satisfied ===
The character is free of Lust, finding it easier to concentrate and bolstering their mental clarity.
=== Enamored ===
The character is artificially or abnormally attracted to someone or something sexually. This behaves in a manner similar to Charm, but with an expressly sexual component; the Enamored character perceives the object of their affections to be extremely desirable and potentially available sexually, causing them to attempt to please, seduce, or coerce them into intercourse. There is no direct control involved, but the Enamored will voluntarily seek to win the affections of their target, making them relatively easy to manipulate. 
=== Frigid ===
The character is emotionally disinterested in sex and cannot gain Arousal from psychological stimulation.
=== Numb ===
The character is unable to be influenced by sexual stimulation and cannot gain Arousal from physical stimuli.
=== Senseless ===
The character has been overstimulated sexually, rendering them oblivious to anything but their own aftershocks of pleasure. This condition normally results from total Mana loss from sexual stimulation and orgasms, though other methods exist. A Senseless character is effectively paralyzed, but may attempt a Will Save to recover.
=== Fertile ===
The character is more likely to become pregnant, experiencing a spike in their normal Fertility. Most species have specific times where this condition naturally occurs.
=== Gravid ===
The character has been fertilized and is pregnant, beginning their gestation process.
