Guys how do you feel about smaller girls/boobs?

I'm a petite girl. I weight about 105 lbs and i'm small. I'm 20. My breasts are not very big i'm a 32 A and people tease me about it. Namely guys I work with for no reason. A lot of People say i'm beautiful. I do get asked out but I feel very sad because guys have been mean to me and I feel ugly. So should I save my money to get them done?
