As someone who has always had a thing for ankles and eyes, I have never been a committed mazophile. However, if I were to express a preference, then it would be for small, pert breasts tipping slightly skywards. Breasts that have none of that blue-veined, bovine-maternal aspect: breasts that make you want to smile, not suckle; feel like having fun, not being rocked to sleep.
For to be honest, I find the thought of adult male babies squirming and letting themselves go in an ecstasy of Madonna-worship, as they kiss and nuzzle in perverse exaltation between the milk-heavy breasts of an ersatz nurse or nanny, somewhat disconcerting. And one suspects that the women who hold and press their infantilized lovers to their bosom, if thrilled in part to have a man so helpless and in their grasp, nevertheless in some corner of their female soul despise and hate them with savage contempt.
As Lawrence notes, it's one thing for an infant to drool and dribble at the sight of a big pair of tits, but for a grown man to be pornographically reaching out for child-gratification is shameful and disgusting.
