Especially on the A.T. where women have practically unlimited choice in partners, sexual selection is largely determined by genetics. Most women will choose a sex partner based on his genetic traits alone without consciously realizing it, and without regard for other “cute” traits such as an accent or ability to mimic chipmunk calls.
We all know a few lucky guys whose sperm all women seem to be after. Those guys will be sore at the end of the day and the next morning too, and not just in the knees, while the other 95% of male thru-hikers are applying moleskin to their hands.:x
