an alternative security tactic if you're threatened with rape

warning, this entry may leave you with disturbing mental images!

So the odd alternative security advice I got for a sexual attack, and it would seem this is only useful for women, is to pee on yourself - and TELL your attacker that you just did.  The idea is to gross them out.  

Thankfully I've never had to try this, so I can't say if it works, but these are the sorts of strategies women share with each other, and the sorts of things women accompaniers have to think about.
