I found this site a while ago while looking for penis curvature on google. It is not my site so Im not trying to advertise anything. The site says that briefs can make a penis grow curved over time and a lot makes sens. It even says that briefs can affect penis size. It makes sens but it has no evidence of it except the author says its the reason why he has a curved penis. I read about the desease that cause penis curvature but the causes are somewhat unknown. Maybe this is it?

That is the name of it. I had forgot it.
The site though says that briefs can cause a penis to grow curved if it stays in like a certain shape for a period of time.

Personally I DO NOT believe (medical research supports) that your underwear doesn't cause Peyronie's. Most men naturally have a certain amount of curve to their cocks. Not at all unusual.
