You're making several big assumptions here:
That it is considered acceptable to the majority of society for women to undergo plastic surgery. There is nothing to support this, a large number of people are against plastic surgery. Especially breast augmentation, because it never looks good.
That a significant number of men would actually consider having a penis enlargement surgery. Being willing to undergo a procedure to enlarge your penis shows a level of vulnerability that most men are not willing to even consider.
That our society allows for women and men to be equally sexual. Women who own/use sex toys are considered adventurous because our society still has this hangup about women being allowed to be sexual. It is anticipated that guys masturbate, but a woman who is open about her masturbatory habits is still often considered a slut. This provides a view that those who are willing to ignore such a label are adventurous. As I said, it is expected that guys masturbate, so it would be viewed that a guy who includes physical aides (meaning toys and the like, not pornography) is probably overdoing it.
And your biggest incorrect assumption: that any of us have any desire whatsoever to suck your cock, regardless of its length. We don't. Really, put that thing away.
Don't base your views about society on what you see on this website. Every category here has its own politics and ethics, so the support for an issue you see here is not representative of how society as a whole views the issue. This is a site of opinionated crusaders. Be careful, many of them are morons.
