A couple friends and myself were discussing whether or not you (a male) would consider it cheating if your g/f, s/o, wife had sex with another woman. Naturally there are some terms here we came to: 1) She has no feelings for the girls. She was just horny and curious and wanted to have fun. 2) She told you about it after it happened... (let say the next day) 3) The girl was a good friend of hers 4) She still wants to be with you and doesn't think it's a big deal. It seems there is a division in how people feel about this. One guy didn't care and he basically said it was cool and just meant chances of a 3some were better now and he didn't consider it cheating. Another guy said he would probably feel betrayed and like he was cheated on... Like he wasn't totally satisfying her needs, etc.. I was kinda on the fence with it. In one sense it could be viewed a turnon, but on the other hand there is something shady about your g/f, s/o, wife having sex with another girl and not consulting you about it first. What does OT think?
