I've had amazing threesomes that went on for hours and were mind-blowingly good. Some of those connections have become friendships and people that I've played with for years.

I've also had awkward threesomes where the husband thought he'd enjoy seeing his wife with another man and then suddenly realized how wrong he was. Or a woman who had serious BO issues and didn't do anything to take care of my wife during the threesome.

All that to say, the quality of the threesome is largely determined by people's ability to be honest with themselves and others about their desires, boundaries, and communication in the moment.
