Ladies, get in line: Zac Efron is single, and he's open to going all the way on the first date -- and he won't think you're skeevy afterward. Really!

The star of 'That Awkward Moment' opened up about relationships and, yes, sex on the first date.

Us Weekly asked the onetime 'High School Musical' hunk if he'd respect a woman who had sex on the first date. And he gave a resounding yes. (We see you, Zefron!) "Sex is a beautiful thing," he quipped. "I don't object."

As for how he'll find a lady to go on a date with? He says his celebrity gets in the way. He confessed, "I haven't met a girl properly ever." That's what happens when you're a superstar -- when paps hound you at Starbucks, it's a lot harder to get the cute barista's number!

So what's Efron looking for in a girl? "I think every single girl has something different and special about her. You find one who clicks with your vibe," he said. "Fate brings people together. But I think the most important thing for me in a relationship is honesty. In the beginning, sometimes girls don't show their genuine personality."

Got that girls? Be real!
