At what age did you have your first fuck, either ass or cunt?

I was a late developer when it came to fucking, though I had started oral sex at the age of 13. I was 31 and met this guy who became my first boyfriend at a mutual friend's. He invited me back to his for the night, and as I was an anal virgin he taught me how to fuck ass, and also how to take a cock. I made up for lost time after this, and must have fucked over 500 guys now.
