HAVING SEX
Sex is an ability check, using your primary class ability + your proficiency score.
The base DC of a sex check is your 8 + Primary Class Ability + your proficiency score. More experienced targets are harder to satisfy.
Sex Points
When you roll for sex, you gain a number of sex points equal to the difference between the DC and your roll. It is possible to have negative sex points
When you make a sexual assault, the number of sex points you earn is equal to the damage you've dealt.
After a long rest, you reset your Sex Points equal to your level + 10. As part of a long rest, you can have sex and add the result to this amount.
Additional Size Fetish Rules
All the actions under these rules are taken/granted for free. They are as intrinsic to PCs as the ability to gain experience or unarmed attacks.
Grappling
Grappling against creatures of a smaller size category:
You can use your action to try to pin a creature grappled by you. To do so, make another grapple check. If you succeed the creature is restrained until the effect ends.
When you have grappled a smaller sized creature and that creature is within your encumbrance you can move normally. You can move that creature anywhere within your reach.
Sex "Toys"
You can buy sex toy versions of any melee weapon, in the forms of rings, necklaces, dildos and other pleasure objects. The cost is 100 GP + the Base Cost of the Original Item. Newly created characters may purchase a Sex Toy in lieu of an existing weapon.
For example, you might by a Bastard Dildo, which is a massive dildo which is the equivalent of a Great Sword. Or you might by a Ring of Penetration, which is the equivalent of a dagger.
When you attack with a Sex Toy, you deal Sexual Assault Damage. This can be lethal or non-lethal damage.
Growth Magic
If you are a spell caster, you gain Enlarge/Reduce as part of your known spells.
You can cast Enlarge/Reduce a number of times per day equal to your level, as a bonus action. When you do this, you can only target yourself or an ally.

THE CRAZY OPTION
Players can take as make sex talents as they want. They are essentially, free. A player that doesn't take any sex talents at all is Vanilla. None of these talents are supposed to be particularly balanced against each other, they just need to equal or better than taking no sexual actions at all.
