Charlie Puth has opened up about losing his virginity in a new interview with Bustle.

Puth divulged to the publication that he lost his virginity at age 21 to a fan who had attended one of his early performances in Boston and, from the sounds of it, his first sexual experience wasn’t quite as monumental as he might have hoped.

“This girl came up to me and was like, ‘Can you sign my chest?’ I was like, I feel like a rock star,” Puth recalled. The singer added that he “never saw her again” after that night.

“She was lovely, but it makes me sad sometimes because I wish the older version of me was like, ‘Hey, you might want to just make this like a little more memorable,'” Puth said.

Elsewhere in the interview, Puth also got candid about the first song he masturbated to.

“The first song I ever jerked off to was fucking ‘This Love’ by Maroon 5,” Puth revealed. “Now I’m good friends with Adam Levine. [I told him] and he was like, ‘That’s really weird.'”

Most of the time, however, he can’t listen to music while having sex. “I will analyze the music playing in the background,” he told Bustle, “and I’ll start to see the music notes in my head and I will not be able to get hard.”

Ultimately, the singer said, being in touch with his sexuality is a key part of his creative process.

“I’m really horny. I think to be a creative, you have to be a little bit,” he told the publication.
