For quite some time now, when my wife and I have sex, I seem to be having issues when it comes time to reaching my orgasm, and ejaculating. Either it happens too soon, my penis becomes very numb, and I leave my wife unsatisfied. Or, I can't seem to "Get There", and I am left unsatisfied. Our sex life has decreased over the years, due to normal things. Children, scheduling conflicts, stress, etc. However, we have always had a normal, healthy, and ongoing appetite for sex. It's not a matter of not being attracted to one another, and we don't do any drugs, nor drink. So we are thinking it's more a medical then mental matter. We have been married for 8 years, and this has been going on for only the past 2 or 3 months. I'm worried, and so is she. She begins to cry, thinking it's her fault. So not only do I have me to worry about, but her as well. I'm always having to explain and comfort her so she realizes it's not her, it's me. Any suggestions?
