Do most women do this to please men?
Considering how men oggle large breasted women, it would seem that way.
Aside from really bad, bad problems there is (as I understand it)the matter that You lost most of the feeling in the breasts, which seems to be self-defeating if you are expecting to enjoy the attention a man might give to them.
I never hear the feminists warning of any consequences of these "enhancement" proceedures. One of their goals should be to convince women to accept their bodies.
Keep them clean and healthy - that is all they need.
