I am in a 3 year supposedly committed relationship and recently found out my partner has cheated on me. Not only the occasional sex at a few other men's homes, but also frequenting a local park with areas men jerk off and have sex. Now all I can think about when we have sex is him with the other men. Oral sex is going OK, but when I try to fuck him I can't keep hard, even with Viagra and Cialis, and alcohol. My fear is that I obviously wasn't keeping him happy before, so I know he is definitely not satisfied now. Even though I have always been open to having a threesome or other adventurous things, and we have talked about it. We have gone to counseling, and it helped get us to stay together, but not in the sex category. I just had this idea his ass was mine and now feel like I am being compared to these other men. Has anyone gone through this and got "it" back?
