The `In My Head` hitmaker - who is currently single - admitted as well as being adventurous in the bedroom, he and his former college roommate once had a bet on who could sleep with the most women in one term.
He said: "Me and my roommate in college bet o who could sleep with the most women in one term. I won by far. I think it was like, six.
"I-ve had foursomes. It`s all in good fun. I`m not in a relationship or anything, so it`s fine."
The 22-year-old singer also explained as his mother has always urged him to be "a gentleman", he is keen not to hurt women them by misleading them if he only intends to have a one-night stand with them.
Jason added in an interview with Celebs on Sunday magazine: "My mother wanted me to be a gentleman, and I am always.
"I`ll never sell somebody a dream - if I`m not into it then I`m not into it. If it was just one situation, then I wouldn`t make it seem like it was going to be anything else. I don`t think you should ever mislead anybody."
