Well, FC, first you have to actually have girls look your way - then they notice the finer points of one's physique.
Besides I wear shirts so tight you can see the vein popping out the actual cloth in the sleeve....
Also, I have no game.... very few girls impress me so I just stand there with a shitty smirk on my face looking like I am too good for everyone which makes it impossible to approach me. Only when some hottie starts hitting on me does anything ever happen....
