Big Sean doesn’t mind sharing his past sexual experiences….

In a recent interview with AllHipHop, the G.O.O.D. Music rapper revealed how his mother walked in on him losing his virginity. (Now that sucks!)

“My first time having sex, I was trying at it for like 30 minutes, and as soon as I got it in, my mom walked in the door and we had to stop. But it lasted for like 20 seconds, and it was good as hell.”

We didn’t know 20 seconds could be good as hell … but you learn something new everyday. Poor Sean.
