Oh gawd....wtf about your secret chubby tummy. You sound like sex pot that any guy would be fortunate to be with...except for an very obsessive mind....should I tell him my little secret about the one faux imperfection in my otherwise perfect body?
I advise not to tell him. He'll find out when your 65 and you'll find out about his waist lard when he's 45.
Actually, you sound like the type of woman who'll never have the think waist because you control it. So bully for him to get to marry a brainy woman with the body of a movie starlet.
PS I'm a guy and I'm 5'7" and 142...so, your 137 lbs...might want to get yourself down to 125...you'll lose a half cup size on the boobies, but that'll be okay.
My last gf was 5'10" 135.
