I don't know if anyone can answer this, but it really bothers me, maybe because I was abused when I was growing up, but why do in watching videos, that guys spit into another guys mouth, to me, its just gross, or when guys are sucking, they get slapped, and it looks like ii is hard, to me its a big turnoff, but I am just asking an honest answer as to whey they do it, thank you for letting me ask this
