It's obviously not something a lot of guys talk about but it's possible to lose genitalia in traumatic injuries. I know a guy who uses the same STP packer I do because of an injury he sustained on a spiked fence as a young kid, so he has a sorta shorter stump left over (he needs a little more length to use the urinals). This happens to plenty of folk in the military caught in explosions and the like too. And not all of them jump into surgical options for the same reasons that not all transmen jump to it. My mate has no interest in it because of the scarring where they take the skin from. The way he sees it, he can cope as is and he just has to work a little harder elsewhere to please the ladies

.
So not only do men enhance, packers aren't just for transmen.
