The alpha px7 primal power swagger. Most men want it, but can't seem to reach that level of manly confidence due to them self-consciously being aware of their small penis size. If this is how you feel, don't worry, you are not alone. Many men (including myself at one point) are NOT as massive as you see those guys in adult films, movies, etc. Most men average in at about 6 inches fully erected. Unfortunately for myself, I averaged around 5 1/2 inches fully erected, and I also had that embarrassing TINY flaccid size (where my penis would hide like a freaking turtle)!
If you are really worried about him having no self control at all and getting the thing welded off, you can always go all the way and get a chastity piercing. These piercings are attached in such a way that if he tried to rip it off without the key, he'd severely damage his manly bits - and no man is going to risk that.
