How'd this thread turn into an entertainment industry diatribe? I just skimmed ... but whoever originally was inquiring about that, take my advice and don't try to get involved in that suckhole. It may seem glamorous and exciting from say an outsider, mid-west, pie-eyed point of view but it's a really slimy industry. No real way to explain it all in a short post. And also, if you don't already know someone who's IN, you can pretty much forget it as well.
As to the original subject ... I think it's debatable that every human being has a certain set of needs. Obviously there's hermits and asexuals who kind of throw the whole notion out. I'm not a hermit or an asexual. I just happened to move about 800 miles away from all my friends and exciting things to do and I also married an asexual. So most of the contact I have with friends is through internet and phone and I have very few that I physically socially interact with. If it were up to me, I'd want to be more social but the area I live in kind of kills that. However, I don't feel I absolutely need the physical social interaction to that level to be happy either. The sexual thing is something I've struggled with my whole life. Not having a "normal" body really puts a spin on things, not being comfortable with being typecast in the "female" role puts another spin on things. Having been involved in some bad situations puts another spin on things and has basically left me with a lot of hang ups. I feel like I need physical intimacy but there's no possibly way I'm getting it, so I just try not to think about it a lot.
