for me cheating would be if my girlfriend did stuff with another guy/girl behind my back without my approval... and with a malevolent intent
having said that, im not the jealous type and even my girlfriend did cheat on me there's a lot of things i would forgive... even if she was lost in the moment and ended up doing stuff with another guy... if there wasnt any serious problems with our relationship, i would forgive... although usually when that happens there are problems in the relationship...
ive allowed my gf to fool around with another guy once and it actually brought us closer... but it was done under very controlled conditions and it was allowed... now we're getting to the point where we allow each other to fool around with other people given the right context... although we're not having any sex outside of the relationship.... oral and manual instead
i think people sometimes get way too jealous with stuff like this and it actually ends up having an adverse effect on the relationship.... free communication is the best thing that can happen in a relationship and it makes u stronger... me and my gf talk about people we like all the time (as well as what we want to do with them
and it actually brings us closer
