sure and masturbation will make you blind and touching a frog will give you warts and girls will lose their virginity if they ride a horse.
nothing can make a penis get smaller, or bigger once it has reached full growth. it seems that scare tactics have become a common technique to ward away the young from using steroids and this has leaked into the urban legend domain. Building muscle is good for you and your penis.
No but steroids can shrink a man's "area" and this is probably how you misinterpreted the rumor since many wrestlers, atlethes and body builders use steroids these days and have major muscles.
I do not believe that building muscle makes penis smaller - I think what you are talking about is a myth. However Ido believe that taking steroids makes ur penis smaller due to the effects on the body that they have in them.....
Well, size is a relative measure, so in comparison with a man's muscles, a pro bodybuilder's penis would look much smaller than a skinny man's penis of the same size.
im a personal trainer .
i can tell u from experience i lost a lot of weight and later bulked up heavily with muscle and i gained close to 2 inches extra . the reason is since you lose fat at the base
