The actor talks about his inhibitions, his sex appeal and why you should think twice about dating him

You might be really into Matthew Morrison. Trouble is, he might not be that into you.

“I’m not a good friend right now. I’m not a good boyfriend,” the Glee star tells Details in its December/January issue.

But it’s not personal.

“It’s not that I’m selfish,” he says. “I’m just focused.”

Working 15 hours a day leaves the actor little time for romance. “It’s been a while,” he says. “Meeting people, you wonder, ‘What does this person see in me?’ ”

It wasn’t always so. Morrison, 32, fondly recalls being smitten with the opposite sex as a young actor performing in musicals in New York. “I definitely hooked up with a lot of girls when I was a young guy on Broadway,” he says. “It was exciting. Very joyous and free.”

Still, he remains a bit conflicted about his attractiveness to women. “I’m not comfortable with the idea of my sex appeal, but I know in my job I have to use it,” he says. “I wish I could say I got to this point in my career based on my talent, but I don’t think that’s true.”

The maturity Morrison found on the other side of 30 allows him to be a teacher not just in the Fox show but also on set.

“I am a teacher to them,” he says of his younger castmates, whom he refers to as “the kids.” “I’ve taken a few under my wing.”

And he wishes some of them could be less publicity driven. “I find myself learning a lot from the set,” he says. “I do look at stuff people on the show are doing, and I don’t judge them, but I question it. I say to myself, ‘Keep quiet.’ Fame. It’s like a handgun – in the wrong hands, it’s dangerous.”
