Lets face it, having big breasts contributes a lot more the aesthetic/visual appeal of a woman's body, where as having a big penis doesn't. Unless you wear really tight pants and women enjoying eyeing your large package. So, I don't think that's a very fair comparison... Anyway, my point is that getting a boob job can obviously change a woman's overall appearance & figure (regardless of whether or not she's naked) so, if a woman is not satisfied with her body and she believes having bigger breasts will improve it, getting implants can raise her self esteem. Wanting to improve one's self esteem is something that people want to do for themselves, not anyone else.
