I may get flamed for this, but I figure SF is an openminded town. I'm visiting next month and looking for a provider into incest roleplay, as daddy's girl or little sister. Extra points if it's a real-life turnon! Reply or email me, thanks . . .

Most of us won't respond to 411's from people posting using an alias.  Provider safety is an important issue and I wouldn't want to recommend a provider to someone w/a hidden ID.  
My suggestion would be to repost with your TER handle.  Don't worry about the roleplay idea, none of us are that judgemental when it comes to anything between two consensual adults. If you're still ashamed, then PM one of the local hobbyists here who have some good BDSM and/or fetish reviews.
