I don't know if this fits here but here is my story:
I remember the moment I was in bed for the first time with my first girlfriend. I was 20 and she was 24 and more experienced and guided me along. I ate her out and she guided me inside. I'm in the flesh "vise". I slide in and out and she's getting excited. She cums. I don't. Maybe I'm just "nervous" she says. We get together a few more times and I just can't cum inside her. A few years later I get another girlfriend and she's enjoying it and I'm not. I start to feel like a tool for her enjoyment.
I meet my future wife and we hit it off for a week. She talked the entire time and finally she asks about me. Now having this history I explain my experience to her. We tried different things including those that usually turn me on. They only go so far. She had me visit a urologist. I'm sitting in the waiting room and I'm the youngest guy in there. He checks me out and says there's nothing physically wrong with me.
At this point I can't even jack off in the same room with her. Eventually we get there and that's my only release. Finally I get to the point where I don't want to be inside anymore. What's the use? It does nothing for me. My wife and I eventually split up. A few months later I meet a new girl and tell her my problem. I eat her out to make her happy but I don't penetrate her. She questions if I really like doing that. I say I do but I don't. She finds another man and that relationship ends.
At this point I'm pretty devastated. I wonder if I should bother with another relationship. They all seem to end the same way. I meet another woman who plays my games. Things are going well enough we get married. Then all of a sudden the love disappears. I'm devastated yet again but eventually it comes back to the lack of insertion.
So here I am at 52 and single but no longer looking. I can barely get hard anymore, even with masturbation. I've come to grips with who I'm not but am not sure of who I am. I'm definitely not gay. Women just don't turn me on. Things they wear do. Does that make any sense?
