I just think that's what you would do. You've got a gorgeous face, a great body, that humongous dick – of course you'll walk around naked as much as you possibly can, it's certainly what I would do. And if you're gay, which he is, then absolutely it's advertising, making sure everyone knows it's available for your enjoyment and entertainment. Being an exhibitionist seems only logical when that's what you've got to exhibit.
Even the "celebrities are usually more discreet" aspect doesn't really affect him – he's not such a big celebrity that this would cause him any problems. Hell, he's probably more famous for his off-screen reputation than for his on-screen skills at this point, and "the biggest dick I've ever seen, I couldn't believe it" is hardly a bad reputation to have, so hell fuckin' yeah show us it all, I'll say thankya and ask for more.
