wanna talk about Sex ?

I'm a little worried - it seems that for some reason the word has gotten out that I'm good at talking about Sex.

Let me qualify that - the word seems to have gotten out that if you want someone to speak to your youth group or young adults - that I'm good at talking about Sex.

In my last church we had a four week series on the topic - we called it 'Sex Fest' (the service was called 'Festival' - hence the 'Fest' part).

The service was aimed primarily at 14 to 30 year olds and we had a lot of fun with it. In fact some of what we did bordered on irreverent (it got pretty wacky) but the aim of it was to get people talking about a topic that Church often largely ignores - except when its says 'don't do it'.

'Let's talk about sex, baby
Let's talk about you and me
Let's talk about all the good things
And the bad things that may be'
- Salt-N-Pepper

I think churches should take Salt-N-Pepper's advice.
We had a lot of fun, but in the process took a good long look at what our culture says about sex (the truths and lies), what the bible says about it, the realities and pressures that we face with it, some of the health issues etc etc etc

Anyway - since that time I've had calls from a number of people who've heard about it and wanting me to do something similar in their churches/camps/youth groups.
I've got another one in the next week or so and I thought I'd open up the topic for discussion here and ask you if you've seen any creative ways of teaching young people about Sex?

Have you seen any good resources? Any ideas or thoughts? Anything goes (well almost). Looking forward to your thoughts and experiences in comments.

Update - here is a starting point that I've already found. It is four MP3s of a record (remember them?) from the 1970's of a Christian educator. They are quite hilarious. Here are the links - its worth the download.

- How Babies are Born- Girls and Menstruation- The Problem with Growing Boys- The Marriage Union
