Charlie Puth claims he wrote a song during sex: ‘I should have focused’

It was a real banger.

New Jersey native Charlie Puth claimed Tuesday that he wrote the song “Marks on Your Neck” — from his newest album, “Charlie” — while having sex.

Puth, 31, revealed that he was halfway through the deed when he conceived the idea for the song’s melody, reported Interview magazine.

“I wrote the song in the middle of the act, maybe I should have focused on the act a little bit more, but the melody just kind of popped into my head and I actually had stopped and recorded a little quick voice note and then had to get back into the act,” the “thirstiest male pop star” told the outlet. “But that’s where that melody came from. I was getting over somebody and what better way [to do that] than meet new people?”

While the timing may seem awkward to some, it apparently was fortuitous for him.

“It probably wasn’t going to work out with this person and that was what I was energetically picking up, which is OK,” continued the “See You Again” singer.

“It’s all about the experience. And I remember waking up and looking at myself in the mirror, noticing these marks on my neck, and every day they’d heal and fade but so would the person who put them on me. And we went our separate ways.”

“I’m thankful for the experience and maybe they are as well but I just thought it was interesting that a person can fade away at the same pace of the scars on your neck,” elaborated Puth.

The Post reached out to the “Marvin Gaye” singer for comment.

Puth, who rocketed into stardom after appearing on Ellen DeGeneres’ former daytime talk show, has never shied away from being sexually liberated.

“I have always loved being naked,” the “very horny” singer told the outlet. “I really do have kind of a nice butt.”

“What’s wrong with liking your features? I have really long arms and abnormally large hands,” continued Puth. “That’s probably why I play piano. Even today, I woke up and it’s kind of fun to look at yourself naked and admire your body.”

Although Puth does love feeling liberated, he knows that there is a boundary that he can’t cross.

“I’m not going to ever be inappropriate and naked in front of people who don’t want to see me naked,” explained Puth. “But If I’m in my backyard, there’s a lot of trees back there and I know that no one’s looking in, I feel safe. You get a lot of vitamin D. Is that what the sun gives?”

The heartthrob is currently on tour for the album, which he describes as “a lyrical self-correcting-of-bad-habits record.”
