I know that every penis is different and erections vary from person to person. I read that some guys can't move their erections much without feeling a little pain while others can. Also, some guys can bend their erections a little while others can't. I'm one of the guys that can move his hard erection in any direction and can even bend it a little at one particular place (but not much). And still, despite that, I'm able to penetrate a vagina or balance a towel on that erection. So just wanted to clarify is this normal?
