As far as Im concerned any sexual behavior should have at least an R rating. Keep it private and away from kids, and no one should be allowed to bother you about it. Insist on going public, and we've got a problem. For normal heterosexuals, this means keeping your damn clothes on. Guys: keep your pants from falling down over your underwear, and ladies: a little cleavage and leg is nice, but more is not always better. And if you must kiss each other in public- keep it short and respectful. No grabbing boobs and ass. This "rule" would preclude gay marriage, gay parents, gay adoptions, gay teachers, gays on TV, transsexual passports, and discussions about gay cowboy movies in the mass media.
