I, too, came close to losing my virginity to a prostitute once because, just like you, I was fed up with being the only virgin among my friends, despite being the oldest. Unlike you, however, I couldn't go ahead with it because I was extremely scared to contract stds. I guess you were lucky with her. You could have met somebody much worse, BUT, as you said, she was a good person and you kind of didn't care about her story and life because you were too horny, which I can understand. Maybe, if you are still in contact with her you should call her and meet up...maybe...I don't know...try to help her. She was obviously suffering, maybe you can do something about it. I don't know her situation

You are regretting it. That's very good because now you have the drive to push through. You can do it, man! One thing you shouldn't do, though:

Don't beat yourself up over it. It happened. You regret. Now move on! Become a better person and a good man to a beautiful girlfriend/wife!

My advice to you if there are times where you feel like you are weak and can't stand it anymore...see a professional. A friend of mine reluctantly went to a therapist once and now he says it was a very good decision! Don't be afraid of it! This community here, can only help you get so far. There is negativity here and very few or even none are professionals in the fields of medicine or psychology etc.

Having said that, you can pm me whenever you feel bad!
