I think cause when it comes down to it, it is what our genetics seem to be programmed to focus on (breeding) doesnt matter your orientation you're still generally build to fuck. Like a baboons ass or or flowers colors it comes down to making your self more appealing. It also defines the difference between a man and woman so the "MORE" man you are the more important you are. even if it is just to your self. just depends on your obsession if your focussed on cars you want the best, or if you run you wanna run fastest men are competative and thats just a fact of life.
