Velvet Revolver star Duff McKagan will never forget his first sexual experience because nuns had to treat him for a sexually transmitted disease afterwards.

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" (gonorrhea).

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."
