I have ED and take medicine for prostate cancer. I have not been able to have any kind of meaningful sex in about 7 years. During that time my wife and I have not had any sex together. I have occasionally had sex with another man where I gave him a good blow job; but, no recipocation. My wife doesn't know about this. I have thought that she might want to have sex with another guy but didn't know how to approach me. As they say, it's not cheating if your husband is watching. I would like to bring the subject up and see if she would enjoy that.
