I once dated a guy that was about 50 lbs lighter than me but thankfully he was taller. That's one relationship that I felt really odd about him putting his arms around me! Sweet guy, runners body, but damn, I like 'em w/meat!
I am no way a very small girl, I have the "athletic" body..I weigh more because of muscle mass..so I prefer my men to be a bit bulky also. I mean, they're better in bed to cuddle with anyway..more warmth
