I have always been a really slender built guy. In high school I maxed out at 110 lbs, even after hitting my growth spurt and going from 5'5 to 5'9 in one summer.
I remember the first time I said I wanted to get Pec Implants was when I was 17 years old, and started my first job as a lifeguard. One thing that I always have been very self conscious about was my rib cage. Not that I was slim...
