Hey guy. The only thing that might be worse than the creative liberties guys take when measuring their dicks might be the ones they'd take when measuring their balls. The first question is, how do you do it? Well, there are some threads on here that get into quite a bit of detail. Still that doesn't much matter: when the "results" come in they will neither be trustworthy nor verifiable. My advice is enjoy what you've got and take every possible opportunity to do your own independent research. Ciao.
