Comic Todd Glass came out gay Monday during an episode of WTF with Marc Maron.

Glass, 47, is best known for competing on the second and third seasons of the NBC reality series Last Comic Standing. He's appeared regularly on Jimmy Kimmel Live!, Late Night with Conan O'Brien and Louie.

On the podcast, Glass told Maron that he decided to come out publicly in an effort to help troubled gay teens who are considering suicide.

“I cannot listen to stories about kids killing themselves any longer and not [think], 'When are you going to have a little blood on your shirt for not being honest about who you are?'” an emotional Glass said.

Fear, not shame, Glass insisted, kept him from publicly acknowledging his sexual orientation. He added that he could see himself “reverting” in some situations.

“As much as I told myself coming here, 'Get over it. It's not a big deal.' That is true. I needed to tell myself that – fucking stop it. But also I can spend a lot of time saying, 'This didn't happen overnight.' This happened, you know, 25 years ago when I started to not be honest with who I was.”

“I don't think tomorrow if I was somewhere – you know, whenever you need a fake scenario, I can never come up with it – but you're somewhere and someone says, 'Who's this for?' I'm not going to be able to be at the department store and go, 'Oh, it's for my …'”

“Roommate?” Maron asked. “Is that what you would say?”

“No, I won't say that, because that's embarrassing. I will not be that guy. You know these guys, they're like 70: 'My roommate.' 'It's my accountant.' Accountant? Really? He lives with you? 'We're very close.'”

Glass said his parents are “cool with it” and have known for about 15 years.

Glass also hosts his own podcast The Todd Glass Show on the Nerdist network.
