I am really sorry about things that have happened to you hon. first though I don't think an internet sex site would be the proper way to get help for your issues. yes I can imagine all kinds of weird people on there. I don't think I would feel safe there at all.
I think you should really talk to your therapist about this. I think with work with the T you can get thru this. they are able to give you good advise on how to move on.
