Malik, 23, made the announcement by sharing a shirtless snap on Instagram and said the song is about physical intimacy.
"I think I'm pretty black and white about what it's about. Everybody has sex, and it's something people want hear about. It's part of everybody's life, a very BIG part of life! And you don't want to sweep it under the carpet. It has to be talked about," he said.
The singer also revealed he would consider doing a One Direction reunion in the future.
One Direction continued as a four-piece and went on to perform their world tour and record a fifth album without him.
