Hi Anon!
I've read through everything you've written. I have to commend you on not acting on your impulses up until this point. They seem pretty strong and hard to deal with. I think you also have a pretty good understanding of where this comes from (displays of masculenity and such) Interesting that you found a woman that you had no intention of raping. Is it because you liked her on a personal level?
You mentioned that you're not opposed to dating sites. Did you know that on BDSMdating, there are options on there you click if you like to roleplay rape/victim? I would not have mentioned this if I thought that you were more geared towards "hurting" someone sexually....but I don't see that in you. You take lube, you take condoms...obviously you're not really wanting to hurt anyone and care somewhat about minimizing what damage you would be doing. You seem more caught up in the atmosphere this situation would give. So maybe finding someone that would like to safely roleplay this would be fulfilling to you. BUT, if you're caught up in the moment and she wants to stop, could you stop? Because if not, then you can be charged just the same.
Scientifically, paraphiliacs have a lot of testosterone in their bodies. Prozac (Fluoxetine) reduces the testosterone levels. If you go for a prescription, they may try to talk you into newer brands, such as Welbutrin or something...these DO NOT lower levels. So you can just say you've been experiencing depression related symptoms, have done your research, and wish to try prozac and nothing else for now. If your dosage is too high, you'll lose your libido altogether, which then could discourage you to take it. I think you need to start with a little bit and just reduce it to the point where you are no longer following women.
As for your friend, if he's a good friend that you don't want to abandon, why don't you let him know the seriousness of your state of mind. Tell him that you're struggling with it and while it may be just conversation to him, you have to work hard to restrain yourself. So conversation needs to omit this subject. At least until you get it under control first.
How does that sound?
