If your sex drive is fine then you aren't eating enough.
My sex drive is through the damn roof and its really hard to get big. I often wonder just how much of it really is genetic. I suppose if I did some supplement I could gain easier, but I'm ok being lean and strong.
"When I see guys working out for cosmetic reasons, I see vanity exposing them in the worst way, as cartoon characters, billboards for imbalance and insecurity. Strength reveals itself through character." -Henry Rollins
