idea, but Wikipedia has a lot of that stuff already.  How do you see what you're wanting to do as differentiating itself from that?  Other than focusing specifically on sexuality?  I mean, for example, you can find entries for just about any porn star you can think of; there are articles on HIV/AIDS, porn, etc.  If you want to go to that effort, IMO, there needs to be some compelling distinction between what you can already find on Wikipedia and what you'd be producing, don't you think?
