Theres nothing that great about sex never was. What usually comes from it? Sweat, fatigue, and dirty linens, then later unwanted pregnancies, and, of course, today theres the health angle.
As for gay sex in particular: Nothings really that great about it. Its very uncomfortable and many times vastly more complex than lovemaking in heterosexual counterparts.
When a boy and girl decide they are going to have sex, they roughly know what to expect. But before two men have sex, they practically have to hold a board meeting in order to figure out the agenda of what theyre going to do.
