Since dday 3 months ago my husband (the unfaithful) has had times when we were having sex or at least playing around that he either couldn't get a full erection or lost it. He says he doesn't know why this is happening. He's never had this problem until after he confessed to the affair. He even had sex with me during his affair (I did not know this at the time) and physically speaking there was no issue. Do you think this has anything to do with the AP or affair in general that he's just not aware of? And what should we/he do?
