want bigger penis? hahah well from my experience with locker room change rooms...
1) fat guys don't have bigger penis's. You would think big fat guys (tall included) would have large fat cocks, not so, they're usually not very big at all.
2) old asian men surprisingly have really huge wangs. Who would of thought.
3) short white guy who is 40ish and works out quite a bit, has huuuuge penis.
I don't stare or anything, it's just things I notice. Whether or not these people enhanced their dick or if they grew engorged with age I don't know.
You could probably do enlargement exercises if you were young, but if you already had a gf I don't think it would be fun for you to waste all your erections on making your dick bigger when she would probably just be happy with you fucking her anyway.
I have hit the -EXTREMELY- illusive G-Spot (oh so good) and I'm not saying my dick is small but as long as you're over 6' you should be OK? ha...
