Recently, about 6 months ago, my shaft skin started to feel tighter. I'm circumcised, and i'm 25 so i'm pretty sure ( unfortunatly) that my penis has stopped growing. I've never had a problem with a tight shaft skin before, up until about 6 months ago, like i said. I had never mesured, until recently and i'm just under 6 and a half inches, but it looks the same so i'm almost sure it's not some kind of miraculous growth spurt. anyone have any idea what it could be? i moistureize normaly, and haven't changed any "habits".
