Guys that are naturally thin are lucky in my opinion, but most of them hate it - they try and try but can't thicken up. Fellas, there a worse hands to be dealt. Not having to watch what you eat, or how much, is gold. I wish I could do that. If I stopped working out and ate the same, I'd blow up overnight...lol.
Slim Jim's also tend to be great in bed. All those legs everywhere. Bending and stretching - it's enough to make a man promise he loves you (even if only for the moment).
