Has me thinking...
In a nutshell, the overall question of this is "Why do girls HAVE to wear shirts everywhere or at least something to cover their breasts"
To get down to the matter, men don't wear shirts everywhere. Girls do. It's globally known that women cover their breasts. But why? Think back in the primeval days, BC days, etc. Men wore no upper body clothing unless it was winter. Neither did women. What changed to the point where it became so wrong for a woman to be shirtless? Back then it was ok. Why did it change over time? We still use basic morals and knowledge. We don't keep the everyone can be shirtless custom though. This is less on the "tits" matter, more on the why. It couldn't be because they get big and they want to cover them. I've seen fat ass niggas with tits bigger than my fist and they don't give a fuck. I mean, yeah, it's nasty. Why aren't they wearing a bra? Why is it immoral for any woman, flat or well-endowed, to be topless? By flat I mean piece of cardboard with a bikini top on it. Flat. They still wear shirts and bikini tops. It can't be the whole "having or not having breasts" thing, as we can see.
My overall question is: What changed from shirtless is accepted to shirtless is forbidden?
Not to sound pervy, in any way. This has nothing to do with breasts, more to do with the immense change over time.
