No, I wouldn't, but that's not to say I haven't. Doesn't make sense? Sure it does, "girlfriend" means different things to different people at different points in their lives and different relationships. To some people a "girl friend" is just a girl that's your friend but to other people a "girlfriend" is a soulmate, the woman he's going to marry, the woman he's in love with and all matter of degrees between the two. I've never watched a woman that I love/loved suck another guys dick, nope, didn't happen, isn't happening, not going to happen. BUT, I have watched girls that I was friends with suck other dicks. Then mine, then I fucked his girlfriend (whatever that word meant to him), then double doggy with high fives and ass slapping and other merry making, good times, but I prefer being the guy that's getting head from another guy's girlfriend.
