Threesome with my friend and wife but couldnt stay hard
Went out drinking with a group of friends before it was left to just us 3. We were all pretty drunk and I started getting handsy with my wife before we all ended up back at our place. My wife managed to get him to admit hes had a tiny crush on her since we met and we decided to have a threesome. It was a pretty spur of the moment thing, we were similar sizes too so I was comfortable with it. We were taking turns, but over time I was having trouble staying hard and eventually I couldnt use it to fuck anymore at all. He "tagged in" to help me and finished her off so she could cum. By the time they were done I was able to at least jerk off onto her but I was so fucking embarrassed. He privately poked a bit of fun at me the next day and she has said she totally understands but I cant stop thinking about it. Any advice? Did I fuck up?
