jared leto looks incredibly small, sure that physique can pull pussy but so can more manlier higher bodyfat type dudes. Bottom line is if your that skinny your sex drive will be nothing compared to a man that eats more and has higher bodyfat.
I wish i could shrink down that lean and not have the low sexdrive, counting every calorie, and being hungry as fuck, but the only way most could ever get that skinny is with cocaine
