You are not serious, are you?
I know that there are men who prefer a woman who is "au natural". Are you Europian, perhaps? It's been quite a few years since I have been abroad, but I have heard that even overseas they are prefering a clean shaven look.
Other than that....why would you post a pic like that? And why would she even pose in that fashion? Shit, a pic is forever. If that is really your gf doesn't she realize that if you guys broke up, YOU ARE IN POSSESSION of SUCH PICS? There is no shame in the human form, but it is obvious that she isn't even making money from this, so why would you degrade her, or why would she degrade herself in such a fashion?
