Genuinely weird thoughts.

I challenge you to come up with a genuinely weird thought. Something frighteningly bizarre. Like so odd that it worries you a bit that you thought of it. I want to compile a list.
Here is my weird idea:
I am unlikely to ever have sex with someone who hasn't already been born.
By which I don't mean I'm unlikely to ever sleep with a foetus. What I mean is, I'm 28. If I was to enter into relations with someone who is about to be born say next week, for example... well the decent thing to do is wait until they're at least 18. Which means I'll be 46. Which is too old for an 18 year old to contemplate, surely?
And yes, it's true, I had that weird thought and then thought I'd ask you all for weird thoughts to make me feel less weird about the weird thought I had.
It actually stemmed from me realising I'm really not attracted to 18 year olds. I think it had something to do with the under cooked and weirdly dressed twinky gay boy who was adjusting his clothes in the mirror of the Belmont Cinema bogs this afternoon.
Ultimately dude, you might think you look hot but you're in the Belmont Cinema bogs... seriously... put the tickets you've got on yourself down before you get hurt.
Or it might have been the blog on whether not having kids is selfish (thanks Observer) which I read this afternoon.
Something has put me in a weird place mentally, anyway. So make me feel better by proving you're weird too.
