What is the absolute worst advice about sex you’ve ever received? What about the worst advice about sex you’ve ever heard? The Say What?!?! contest, sponsored by Isis, Inc., MTV, Funny or Die and SayNow.com asked young people between the ages of 15 to 21 to talk about the worst sex advice anyone’s ever given them. The answers are humorous, painful and at times, utterly ridiculous.

Thankfully, we’ve got the Sex::Tech folks to make sense of it all.

The winners will be present at the Sex::Tech 2010 conference, an annual event bringing together reproductive and sexual health professionals to explore the best available technological and social media tools and methods for reaching youth with culturally appropriate STD/HIV prevention and sex education interventions.

For those who just can’t wait, here’s a snippet of the contest’s winning entry:

I caught my brother with a girl in the room. I asked him what he was doing and he said, “I guess you’re old enough. Don’t ever let a guy put his ‘thing’ in you because you’ll explode.” I’ve been scared every since and haven’t done any of those kinds of things.

Join us here today on Rewire to watch the Sex::Tech keynote address and check out the Say What?!?! contest winners live from 9:30- 11:30 am EST (Friday, February 25).

Tune in on Friday and find out just how bad some sex advice really is and, more importantly, what honest and up-front sex education can truly look like.
