The 23-year-old said that he "accepted" his newfound sex-symbol status and took advantage of the female attention surrounding the 'Lightning' singers.
Parker (bottom left) told The Sun: "I just accepted it when I got into the band. I knew if I became famous I was going to get girls. I loved it. For the first six months I was sh*gging everything.
"In the early days, I actually slept with five girls in one night. It was in two different rooms. I remember running around going: 'What's happening in this room? Hey! I'm there!'"
Fellow band member Nathan Sykes (top right), who admitted that he "warmed the floorboards" with a girl at Parker's recent housewarming party, added that he had been a complete flop with the opposite sex before finding fame.
"Girls do pretend they find us attractive now we're famous," the 18-year-old said. "Before our number one I couldn't pull a bird for the life of me.
"When I was younger, I'd be like, 'She's about a two out of ten! Great!' Now all of a sudden I'm getting girls who are an eight out of ten."
