For a man who is bursting out at the underwear seams, it’s hard to believe that Colby Melvin came out of the closet two short years ago.

“It was the day after my first experience with a guy,” says the 24-year-old then-Houston resident. “December 28, 2010—I know the date because it’s actually my mom’s birthday. It was my first experience with a guy. I was like ‘That’s it!’ The next day I came out to all my friends and family.”

Colby says he’s one of the lucky ones, as his family was “incredibly supportive.” And don’t let those boyish good looks and pinch-worthy cheeks fool you; Colby came out with a mission. The now-West Hollywood resident is an “exclusive,” full-time Andrew Christian underwear model, a goal he set his sights on years ago. He’s also an activist for FullFrontalFreedom.com, taking his clothes off one LGBT cause at a time.

“I had worked with a couple of underwear lines,” says Colby on pouch ambition. “I’ve been a fan of Andrew Christian for quite a few years. Probably back in April I submitted a picture and they put it on their facebook page. They got an overwhelming response; they called me back, said ‘We want to work with you.’ I came out to L.A. for Pride, did a bunch of things with them, and less than two weeks later I had my one-way ticket to Los Angeles. It was the best decision I ever made.”

Soon FullFrontalFreedom.com called, and a star was shorn. “My goal has always been to get into the LGBT movement and get involved with causes,” says Colby.

“Yes, I’m taking my clothes off, but I’m building this following to ultimately make a difference. I want to see the middle man. I want to reach out to the other eighty percent of men, not the old guys in suits. We are reaching a completely different audience.”

No s***! FullFrontalFreedom.com produced one of the funniest—and sexiest—anti-Romney videos this election season, a clip starring Colby and some other clothing-impaired guys that went viral faster than the dudes stripped to their skivvies.

Colby, who’s not voting for Romney, says, of the video, “One of the guys in it had done scenes for Randy Blue. People say things like ‘How can you be taken seriously?’ My response is ‘How can we have a man for President who doesn’t want to run half the country?’”

Colby, who’s as cheerful as he is adorable, adds, “For me, it’s about spreading the message. I want to be completely transparent about who I am. I didn’t move out to California for fame, or to be popular; I came out here because this is the place I thought I could make a difference. I can reach a lot of up and coming gays and say it’s okay to accept yourself.”

When I asked Colby what a guy like him does for fun, living in West Hollywood and all, he answered, “I work. If I get a call asking me if I want to hang out in my underwear and be paid and talk about the stuff I care about…then, yeah; I work for fun.”

Now I know why they call it “hard work” :)
