Justin Bieber has revealed that he believes people should only have sex if they love the person they are with.

The teen star is currently in a relationship with Selena Gomez and has been for some time.

Speaking to Rolling Stone, Bieber said that he advocates sex but only if you're in love with your partner. He said:

"I don't think you should have sex with anyone unless you love them. I think you should just wait for the person you're in love with."

Bieber meanwhile revealed himself to be a very attentive boyfriend, adding that he makes sure to notice the "little things" - like when Gomez gets her hair done. He said:

"I make sure to do the little things, like noticing when they get their hair done or when they change their nail colour. Also saying things all the time - like, 'You're very pretty', 'You're gorgeous', things like that."
