I'm kind of a smaller framed guy and my girlfriend is on the curvier side and I just found out she weighs more than me. I'm 5'11 and I weigh 156lbs and my girlfriend is 5'10'' and she weighs 168lbs. She has always been sporty and athletic so she's in good shape I just don't want her to feel self conscious because she's bigger than me because with most couples the guy is bigger and stronger. She can lift me a lot easier than I can lift her. Is it alright for her to weigh more?
