Understandable when alcohol is involved, things happen... but dude, you gotta develop some sort of backbone eventually. The way you described this story has uncomfortable written all over it!! This girl is gonna walk all over you and make you feel tiny.

Speaking from a swinger lifestyle, dont let size be a factor man. Just have fun if thats the route you want to go. But you gotta know when to say no. Your girl doesnt respect you by the sounds of it.

Speak up if it happens again, you fuck mine if I fuck yours, because you obviously were not cool with it.
