Comedian Amy Schumer can talk about sex on stage for hours. In interviews? Not so much.

“What do you want me to say? I don’t know,” says the 31-year-old New Yorker, when asked why she thinks sex is so funny.

So if you want to hear her talk about sex, go to the Charlotte Comedy Zone, where she’ll do four shows over the next two nights. If you want to hear her talk about how she’s constantly being asked to get naked … you’re in the right place.

Schumer – who broke out on the Comedy Central roasts of Charlie Sheen and Roseanne Barr and then scored big with her special “Mostly Sex Stuff” for the same network – is often described as having “wholesome, girl-next-door looks.”

And yet the wholesome girl next door keeps taking her clothes off. Anyway, enough teasing – on with the interview.

Q. Where do you think you’d be right now if not for the roasts?

I’d probably just still be on the road, doing exactly what I’m doing now … but making less money.

Q. What can you tell us about your show?

It’s dirty. It’s dirty.

Q. Speaking of dirty – you’ve been compared to Sarah Silverman, another famously raunchy female comic. You OK with that comparison?

I love her. She’s a friend. I don’t mind being compared to her at all. We’re both cheery, and we both do racist jokes.

Q. Do you find your audience skews more heavily toward one gender?

No, it’s really 50-50. There’s times when I think both men and women feel alienated at my show.

Q. What do you have on tap for the near future?

My TV show (“Inside Amy Schumer”) starts April 30th on Comedy Central. I got a book deal. And I’m going out to L.A. after Charlotte to do a spread for Vanity Fair.

Q. Oh, that’s cool. How do you feel about modeling for magazine photo shoots? (Schumer has been photographed for Cosmo and British GQ.)

I mean, I talk about sex and I’m not shy, but it’s funny because I’ll show up for the photographs to be taken and I will just show up in jeans and be like, “What are we doing?” They’ll have a rack of clothes, and they completely ignore that I’m a comedian. When I went to do British GQ, it was just denim shorts … and they were like, “Yeah, just pick a pair.”

Q. You wound up posing topless for that one, and you also took off your clothes for Cosmo, right?

Yeah, any photo shoot I’ve ever done, the clothing has been minimal. I think they just ignore what it is you do. They’re just like, “A girl’s coming!” They’re used to models, and I’m like, “Um, I’m a size 6, let’s roll that rack in.” … I’m very comfortable in my own skin, but it’s weird to be in that world that’s not yours, where the standards are different.

Q. So how are you preparing for the Vanity Fair shoot?

I’m not drinking this week. I might get a spray tan. I just know better now. (In the past) I would be annoyed because I wouldn’t have any warning. ... I showed up to film all these videos for Cosmo, and (found out on the spot) the idea was that I was basically naked the whole time.

I would have loved to have even two days’ notice, rather than just show up on set and have them be like, “Take off your clothes!”
