The ‘Yeah!’ singer claims that gaining fame at 13 – signing with LaFace Records after competing on talent show ‘Star Search’ – made sex more available to him much earlier on than most teens.

However, Usher admits that he didn’t have a clue what he was doing at the time. He revealed to ‘Vibe’ magazine: “I started having sex at 13. I didn’t understand why I was having sex until I was about 17 or 18.”

The singer, now 32, explained: “Let's just say this - I didn't realise that you start to finish. Up until that point, I had never finished. I just always had sex. I understood that I gotta make sure I please this woman, and I hope that her making those noises aren't pain!”

Usher is currently promoting his sixth album ‘Raymond v. Raymond’ which features international hit ‘OMG’.
