Nick Jonas' sex life has ''dramatically'' changed his music and made his work more successful.

The 24-year-old singer - who wore a purity ring with his brothers in his younger days as a Disney star - has admitted his sexual encounters are ''important'' for him and his music because they have led him to become a better songwriter as he can sing about his experiences with ''more reality''.

Speaking about his hit tracks to Wonderland magazine, the dark-haired hunk said: ''Any time I approach writing a song I think about the fact that since I started having sex my creative life changed dramatically, and my ability to write a song with more genuine depth, more reality.

''Sexuality is important as an artist, to embrace and use it as ammunition in your creative life, and understanding that part of your life, and how it makes you feel.''

Meanwhile, the 'Jealous' hitmaker - who has previously dated Miley Cyrus, Selena Gomez and Olivia Culpo - has admitted he would be open to being spanked when he gets steamy under the bed sheets.

When previously asked if the raunchy act would be something he would be interested in, he said: ''Yeah, absolutely. I've got a firm ass.''
