I've been there. We used to do it alot back in the good ol drug and alcohol days and it eventually caused problems. For women its the emotional connection they don't like seeing their man pay too much attention to other chicks. Mine had a strict rule no kissing! BTW it was always with women, sometimes 3-4 at the same time. Never men. I personally could not see my ol lady being fukked by another man, double standard, you bet your ass. Thats just the way it is. We don't do that anymore, been years, I wouldn't even entertain the thought. Just show your lady some love and stay away from the "life" for a while.
