I lost my virginity at thirteen, says Usher

London: Hip-hop star Usher admits being a casanova in his early years as he says he lost his virginity at the age of 13.

"I started having sex at 13. I didn`t understand why I was having sex until I was about 17 or 18," femalefirst.co.uk quoted him as saying.

"Let`s just say this: I didn`t realise (that) you start to finish (give his partner an orgasm). 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," he said.
