@ F_P_M, you say it man, you say it!
Living near the beach, I see quite a few big boobs that are not covered, they just happen to be attached to the chest of a person looking like a guy. I assume they are moobs, and are thus OK, nobody cares. If the same boob carrier would look like a female, the cops would chase her up and down the beach to give her a ticket for indecent exposure! Which shows that it is not the boobs that are offensive, it is our dirty fantasy that make them that way!
In most native societies in third world countries, the females have their breasts uncovered, because they have not become an object of sexual desire there. I bet those women have the same feeling in their boobs (some are very sensitiv, others are not), as the women in western societies, but their boobs are not seen as sexual objects, just as some body part attached to the chest of a female.
Where did our culture go wrong to make the boobs of western women almost like an extension of her genitalia?
Being not concerned if people see my nipples pocking through a top, makes me almost feel lucky that i was socialized as a male, and was not raised as a person who has to hide body pats that have nothing to do with their genitalia.
As a European, it always makes me wonder why even little girls, who have nothing different on their chest than little boys, are forced to wear something like a bra when they play in the sand on the beach!
