Can I reprogram myself to have orgasms?

Hello Michael: I am a 38-year-old man. All of my life I have struggled to reach orgasm with my partners. As a result, I have lost many relationships. My partners think that they do not satisfy me and some think I might not be able to reproduce. This has caused me to beat up myself and think there is something majorly wrong with me. This problem has greatly affected my life and is one of the main reasons I turned to a life of drug addiction and have no children. I have no problems getting an erection. I am satisfied with the size of my penis and I consider myself to be attractive. This leads many to wonder why I do not have many relationships. This is because I am afraid that once women learn my secret they will no longer be attracted to me. After reading your article about this problem I know that I am not alone and think that I can do something about this. I am the type that has trained myself through masturbation to only orgasm in the both ways you stated in the article and I am a “delivery boy.” My question: Is it possible for me to train myself to have an orgasm during vaginal intercourse? Can I deprogram the way I have taught myself to ejaculate? I would like to have children and not be afraid to get into a relationship because of my problem. Thank you for the article it has given me hope!!
