Friend: Can pre-cum make you pregnant?
Me: Yes - you're an idiot...
I felt slightly bad for such an abrupt response, but really if she had wanted a soft thirty she should have pre-warned me.
Pregnancy test and about £15 later, she's in the clear. Phew!
What completely ruffled me - conceding that someone our age can either not know the answer to this or risk unprotected sex with a new lover - what hope do we have for teenagers and alike...?
