Men are eccentric too, in their own way

We - men - the descendants of the Adam's family, are generally homophobic. We do not openly acknowledge that some other man is good looking and sexy. We believe, that if we do, we might end up being homosexual. And we do behave weirdly, when other men are in compromising positions. Walk into a men's washroom (specially in theaters or airports) and take a moment to observe what happens. There clearly a emerges a pattern in the way men choose the urinal, amidst all the bladder emergencies.

Let's assume there are five urinals in a linear structure. The first guy more or less always takes the corner one (for whatever reason). When the second guy walks in, he will take the farthest away from him leaving the 3 in between free. Now the third guy is almost always likely to take the center one which leaves a 10101 pattern (you see, the number '1' has a metaphorical significance here, but you wouldn't have realized this unless until you have these words in the brackets). Now the 4th guy who walks in has no choice. He thinks twice before taking the 2nd or the 4th spot which are equally optimal solutions . However, some individuals do wait a bit more to check if any other guys is about to zip up. The fifth guy has no option other than to take the remaining one.

Better design

Hence  - the optimal choice would be such the sum of empty urinals between that one and the next occupied ones on either side is to be maximum (this algorithm works even when urinals are arranged in circle). But, I've seen my fellow human beings beat this solution and not choose to use an empty urinal just because the adjacent urinals are occupied! unbelievable, right?! I believe that we are more embarrassed of accidentally seeing someone else's ..you know..than someone else seeing ours. While the above might seem a generalization of the solution, more research can be found at xkcd.

Scientifically speaking, I'd attribute our discomfort in complementing other males to our primal instincts where we see our fellow species as a competition for mating rather than a collaborator. Openly acknowledging another male's superiority is undermining oneself in the society. That's science and makes more sense, but let's not go there.

We are homophobic only when it comes us. But our take on women being homosexual is totally a different ball game. We are more than OK with it. There is a whole industry thriving because of this.

I have a basic scientific question though. Do women find it hot when two guys kiss? Or at least do they get turned on when two guys fight? We do when women are involved in either of the above.
