Here's my opinion of them. I personally would never have one but if your man asked to have one and you feel upset about it, tell him sure, with another man. If he doesn't want to do it with another guy because he doesn't want another guy having sex with you or you giving oral to another guy then say well I don't want you giving it to another female. Also, I think that bringing up using a guy would show if he just wants to have "new pussy". In my opinion, threesomes cause a lot of problems and jealousy so I stay away from them. To the people who have had successful threesomes with NO problems at all, congrats! This is not to throw shade, I promise.
