Hi everyone,
I came across this link the other day to a funny animation regarding chlamydia, worth a look! For once, a bit of light hearted animation - which probably increases awareness just as good as the hard hitting campaigns these days.
It's probably classed NSFW (but it is only an animation!!).
Some crazy positions there, not sure about the headbutting!!
