My girlfriend wants to watch me have with someone else!?

I think this girl really fancies you, and it sounds like maybe you have a lot of friends? and are well known..and maybe she has heard rumors about you or someone has told her something to make her say something like that. I am a girl myself, so I am trying to put myself in that position, and the only way I would let/tell my other half to have with one of my friends or another girl in front of me would be either to test him out and see if the stuff I am hearing is true, or maybe to see how much he actually loved me. Either that or she likes girls?..lol..Suggest to her to have with someone else in front of you..Who knows, Or maybe she wants you to do that so she has something to hold against you later?..Hmm I dunno girls are as bad as men! Just tell her you don't want to do it..you love her and you don't want to ruin what you and her have =] good luck with everything.
