As someone said op might like 50 shades of grey type of relationships. That's fine as people have different tastes. There have to be men who are into it. There might be even ways of finding men who want S$M type of things etc (maybe sites for that?)but they don't have to have be rapists. You don't need to date a rapist if you like to be submissive.

As about wanting to help people to change there are many ways to do that. You can volunteer and help former convicts in many different ways. I think having sex with repeated rapist isn't going to help anyone. Especially if you like rough sex. If you don't worry about your own safety, then maybe worry about his. It's like serving free drugs to recovering drug addict.
