Well the reason I said I wouldnt have full sex with the other girl is because I think thats where the jealousy would start. I would not want that to happen, so unless my girlfriend does something like put me inside the girl I wouldnt go for it. I dont have a problem with her making out with a girl or doing something with a girl if im there and of course the rules would need to be clear, I trust her we have been going out for 4 years. But the jealous part thats what im most worried about, as well as the after, if it would continue or not. Its impossible to know thats why I am looking for some advice.

Lots of people say leave it to the single crowd and I might agree, everyone says its risky and destroys relationship, of course we are not going to run into it his week or anything, it would be months away after we have talked about it for a long time. But hearing everyones opinion is nice to hear the full range of ideas on the topic.
