Has anyone had arousal issue while doing things outside of your relationship? My wife (31F) and I (29M) opened the relationship and have toyed with the idea of a bunch of possibilities and we both have very much enjoyed incorporating these ideas into our personal activites. However, one night a while back while out drinking with my friend (M) and her friend (F) both of which we are each attracted to... the night ended up in a 4some. My friend is attracted to my wife and I'm attracted to my wife's friend so it started out solid. Then for some reason, after starting, my friend and I couldn't keep our soldiers at attention. We all fooled around and tried different foreplays but the night eventually ended with not much having actually been done. My wife and I dropped off her friend and then went home and immediately started having sex and I had no issue there. Could this have possibly just been nerves? Has anyone else experienced this?
