Duff McKagan from Velvet Revolver performing at Brixton Carling Academy, London, England - 25.03.08

The former Guns N' Roses star was 13 when he lost his virginity to an 18-year-old "punk rock chick" and she gave him "the clap".

The rocker recalls, "Three days later I'm at the free clinic, and it's all nuns. And one of them stuck a Q-tip right in my d**k! I'll never forget that."
