You're a big dude. We're all too small bro. You don't know. remember that even though she's your girl, they find ways to fuck with you from time to time. Just the nature of the beast.
You have a great build. Funny that you're girl would say that. Most women like the lean, athletic look much more than the juice monkey, knuckle dragger look..
Don't let it go to your head. You are deisel bro..
