He's the kind of man that doesn't pay attention to minor details that, in turn, cause major turn-offs. For instance, while in the missionary position, women don't like it when men lean on their hair with their elbows making women feel like they are getting a discount face-lift. It seems that when men get their hands on a pair of breasts, they regress to childhood and think they're dealing with toys and not with human body parts. Don't treat breasts like they're made of play-dough, because they're not. Do not treat them like they're some science experiment and that if you squeeze hard enough, maybe you'll be the first guy to deflate a pair of them.
Breasts are beautiful works of art.
Caress them and appreciate their form. Cup them in both hands and softly embrace them. Rubbing your own naked chest against them is always acceptable. There's nothing women like more than men who can appreciate, adore, and admire them as though Michelangelo himself sculpted their form. Stop treating them like they're uncooperative snacks because no matter how badly you want to believe it, nipples are not gummy bears.
