I'm not too sure where to start with my question, so I guess I'll just start typing and get to the question when I get to it. This is a rather embarrassing but awkward, question. I am a 38-year-old married man, who has a very unusual but healthy sex life. When my wife and I do eventually have sex (we have two children) she enjoys it. I on the other hand do not. The problem does not apply to her. It's all about me. My wife will occasionally perform Fellatio. The problem is -- I do not benefit from it. In fact, I cannot keep an erection when she wants to do this for me. Weird, right? I can't ejaculate when she is performing Fellatio. When she is performing, all I do is stare at her. My wife feels I might have problems with relaxing which causes me not to ejaculate that way, I've tried several times to shut my eyes, you know like they do in porn, but still I can't find any enjoyment of this. I have told her stories being with other girls...Prior to being married. I had the same problem. It’s like some kind of sexual block. Do you think that would cause this kind of issue? We don’t do it all the time. I am truly want to enjoy this, but I just can't. What is wrong with me? Have other men experienced this?
