http://theintimacydojo.com is a good beginning. There is also another splinter board, by Cathy from the Intimacy Dojo, that also addresses many issues.
Reid Mihalko seems to be an interesting guy. He offers phone counseling as well. I met him briefly a few weeks back in Dallas and he does have a riveting presence. It's a good start! Here's his site:

I'm actually trying to create a board for just that reason. A board to speak about sex and although I'm hoping that it will be "sex worker friendly", it's not going to be a board about sex workers.
We have THIS board for that!
I'm just having a few problems with trying to get the basics going. I need some website engineering help but haven't gotten that far!
But I hope that my few suggestions will help!
