I'd choose the physique and not worry about dieting........Somethign that big, won't be hard as a rock..... and i don't think you can be completely fully erect....
For all the guys...take the body. To you guys and to put things in perspective, fifteen inches would be like having a baseball bat rammed up your ass. Think about it guys. Too big IS painful. If you guys don't know that, you don't know many women. It's common known fact among men who REALLY do date and fuck alot of women.
15'' is fucking insane and total uncomfortable for chicks, not to mention that is impossible to achieve that length unless you are a horse/whale/donkey or an elephant!
Can't believe some of you actually ponder this...15 inches?!..who needs to be that big? I'll take the perfect body/no diet any day. Along with my 14 incher
