Okay so here is my situation and i don't know if I am normal or what not. I will start from the beginning. When I was 17 years old I went to a prostitute, we where in my car and I had protected sex. I did the deed and I threw away the condom, 30 minutes later had passed and I was paranoid and I went to look for the condom to see if it had any holes. I was dating my ex-wife and before she became my wife she cheated on me but i still loved her and she gave me an std....curable but from the moment on I have always been super paranoid of std to the point that I make my self sick and to top it all up. I got to the Planned Parenthood every quarter to get a full panel of std checked on me even though i do not have sex. I seem to drive all my potential mates away because i get them tested every month even though they are with me. I do not know what is wrong with me. I am currently talking to this girl and we have done foreplay and oral sex but i cannot engage in normal penis-vagina sex. I really think I am loosing my mind to the point that I wanted to have a chemical castration done on me.
