Rapper C Jamm attended a festival at a university recently and is becoming a hot topic for addressing the topic of sex.

At the Dongnam Health Scienes College's festival in Suwon, Gyeonggi-do on September 21, the rapper reportedly gave an impromptu sex education class to the students viewing his performance.  A segment of it was posted on Instagram by one of the students there.

C Jamm started off with, "Never have sex in a DVD room, and I hope that you will use contraception no matter what.  [Having sex in a DVD room] is something you should never do to your girlfriend," recommending she be treated with more respect.  

One student asked how he was so knowledgeable on this, and C Jamm replied nonchalantly, "I know because I've done it.  Why are you all acting like you never did it? Why else do you think DVD rooms are doing well?  It's still doing well today because all of us went there when we were younger and gave them money.  I hope you won't teach these this kind of stuff to younger people and that you'll practice safe love."
