This is probably quite old and I'm most probably the last person to have seen it, but I thought I'd share it because it made me laugh. I haven't played any role playing games in years, and when I did I never quite thought about my character having sex. Well, if you have ever thought about such things there is The Complete Guide To Unlawful Carnal Knowledge For Fantasy Role-Playing Games. A guide to everything sex for rpgs.
There comes a time in an adventurer's life when he/she wants to engage in the act of sex. Unfortunately, most RPG rule books avoid the subject for obvious reasons. A player rolls dice from pottery to dancing, so why not sex?
At first glance, it may seem that a character can have sex for quite a long time. This is true for player characters. They have superior attributes, and thus can perform better (that's why they're great adventurers). However, an average character would have attributes between 9-12. Using the below rules, an average character (10 or 11 in all attributes) could go a minimum of 10 or 11 minutes (rounds) and might be able to go an additional 10 or 11 minutes if very, very lucky (dice deities willing, but don't bet on it).
Personally, I don't need my rpg characters having sex. But that's just me.
