And the good Y chromosome owners don't even realise how often it happens. I remember waiting to get on the tube with a co-worker (male - responsible Y-chromosome owner) and as one bloke got off and I got on, he stared straight at my tits for an obvious duration. My co-worker said "OMG did you see that? That bloke just stared straight at your tits!" - to which I replied "Yeah, happens all the time..." - Co-worker couldn't quite believe it.

Okay it's a completely minor thing compared to some of what you guys describe - but it was just interesting my co-worker had no idea that "most blokes" were like that. Personally I think the poor love was just sheltered ;p
