Is there anyway to tighten loose pubic skin?

I have 1.75 inches of pubic skin and fat and that's at my skinniest. So if I gain any weight it's really not a good thing. Is there anything I can do to get it down to at least .50 the surgeon I talked to said its normal but, I'm very unhappy and don't understand why I'm so loose. By the way my skinniest was 173 and I'm 6'2 I still have some excess skin sure it adds some pounds :(
