Beyder,
Your girfriend is lovely and you should be proud of not only her, but also of being the type of man (wit, humour, good looks, whatever) that can get a lovely girl with a winning smile.
Tranny is right on with is comment above.
Folks trying to psychoanalyze you, and yet throwing subtle criticisms based upon "hateful jealousy" will be all too common. Saying "proud of the boobs you just bought her" and alluding to you having feelings of inadequacy and needing p*nis enlarging ads, are simply a way of pushing you down into the dirt on your way home from school the way bullies like to do. Anyone with half an education (street, common sense, or book-learned) can read right through that.
Post a photo of an "oink" and certain folks oogle. Post a photo of a real girl, and she's a hooker and you're insecure for posting the photo.
I love photos of boardmembers, their families, their girlfriends and boyfriends, their motorcycles, their boats, their travels, and their day to day things they see. Keep posting photos of you and your lovely lady.
Good on you.
