As a New Yorker, I take the subway *a lot*. And all too often I find myself staring at men's crotches. I can't help it. I don't want to look. They're just there.
Know this, gentlemen: I get no enjoyment from my crotch-ogling escapades.
There are several factors that create a bountiful crotch viewing environment on the subway:
1 - Women, myself included, tend to opt for seating on the subway if they can find any. Usually we are carrying heavy bags or are wearing high heels and want a brief rest. Men, on the other hand, tend to enjoy standing. Therefore, we're eye level with the crotches.
2 - There isn't much to look at on the subway if you don't have a newspaper or book. After about two stops, you've read every advertisement in the subway car, and have already exhausted yourself of trying to look busy on your mobile phone. So you find your eye wandering, looking for anything ANYTHING that is more interesting than re-reading ads for hammertoe and bunion removal.
3 - They're crotches! And they're in your face. How can you *NOT* look????
I'm torn in this web of crotchfulness and I can't seem to get out....
