Giants cornerback Prince Amukamara’s teammates didn’t know that he wears a chastity belt underneath his jockstrap — and they’re all supporting him.

“When I first heard it, I was like, ‘Wow,’ ” cornerback Jayron Hosley told The Post Thursday of the 24-year-old’s vow to stay a virgin until marriage.

“But everyone comes from different places. Nobody’s the same. You can’t expect that coming into a locker room.

“He’s doing it for a reason, for something that he believes in, that he feels is right for him. I respect that.”

The devoutly religious Amukamara made headlines this week when he told Muscle & Fitness magazine he doesn’t drink and hasn’t had sex, earning him the nickname “the black Tebow” from peers.

“There’s more guys out there like that than you think,” Hosley said. “Negative publicity seems to get the headlines, but there’s a lot of good guys out here doing a lot of great things.”

“I’m the type of guy, you do what works for you,” said safety Ryan Mundy.

“It’s definitely a window into the type of person that he is and what he believes in and how it helped him get this far.”

Cornerback Aaron Ross: “He’s raised a little different from most defensive backs, but that’s what makes him special. He’s like the little brother in the room.”

Amukamara is engaged to longtime love Pilar Davis, but plenty of New York gals in Times Square Thursday said they’d take a crack at Amukamara in the sack.

“I could pull this off,” said Tabitha Good, 21. “If I saw him I definitely would go up to him and introduce myself. I don’t drink either, so I’d say, ‘I’d like to share a coke with you.’ We definitely will be out all night.”

“I have the male mind down. Him being a prince, that would make me a princess. I like that — it’s intriguing.”

“It would be challenging, but there is nothing like a challenge,” said Phinnia Jefferys, 19. “It would be kind of cool, especially because he has never being with a girl before. If I have to take the lead, then let’s go. The first time is the best.”

Lauren Biala, 19, said she would take it slowly.

“I’d make it special for him. I would cook him dinner, later bring out the candles and give him a massage,” Biala said.

“I’d give it a shot.”
