So...
Today I ran the first session of my Skull and Shackles campaign and already I have a situation I've never encountered before in almost 20 years of GMing games.
One of my players is running a female gnome alchemist who spent her first day on the Wormwood running away from rats she was supposed to be hunting (a natural 1 on her Survival roll) and then challenged Conchobhar to a game of dice without any money.
She wanted to try and win his hat and as he's described as a serial womanizer I had him suggest playing for a night in her hammock, expecting her to turn him down. She accepted and then lost horribly and willing fulfilled her part of the agreement...
Does anyone know where I can find a copy of the Book of Erotic Fantasy? I know that had rules for conception and pregnancy
Highly recommend not going there. just say she does, they did, and let it go. you're only going to creep someone out if you start trying to role play that out.
A quick look across pregnancy sites indicate there's a 2.5% chance of conception from any one given act. You probably don't want to bother with this unless the player thinks it's an interesting plot, as medieval ship life would result in probably a 50% miscarriage rate and there are further options if she didn't want to stay pregnant.
In my pirate game, our first mate is desperately trying to get his wife pregnant. She's a serpentfolk in disguise, though, so that's hard.
Sex, pregnancy, etc. can be a good part of a mature game, it doesn't have to be "creepy" any more than going to an R-rated movie is.
