Credit where credit's due: This is a well-written guide. It's comprehensive and easy to understand, and I've had surgeries that took fewer sanitary precautions than they recommend. That makes it even weirder, because the best way to ensure that you don't get dick dropsy is to go to a goddamn professional. The guide even suggests this several times, and also mentions a few of the many, many ways doing it yourself can go horribly wrong. I don't know what sort of man decides to go ahead with the personal touch after reading these warnings, but I know I'd want him to have my back in a bar fight.
And oh boy, can this ever go wrong. It's suggested that you get a pair of clamps so that, when you make the first hole and start screaming like a little girl who's being mauled by a tiger, you won't accidentally miss your mark on the exit and give yourself a second urethra. If I ever follow the Internet's advice to apply a clamp to my foreskin, the next step in the guide had better be "Question every life decision you have made up to this point as you star in a Bulgarian porno to pay off your gambling debts."
We'll now take a minute to let every male in the audience cross his legs and cringe.
Look, I'm no prude. If you want a genital piercing, go nuts (although not literally). But for God's sake, get it done by a professional. The "jam metal through a stranger's genitalia" industry is probably traumatizing enough without them having to worry about losing business to a self-starting go-getter. Not to mention that if you mess up, you'll have the most humiliating emergency room story ever.
