Well, his name is faux pas here, but W**gfoot once made a good entry on this issue, which I dare to copy-post here. I agree with it completely. xtn
“Sex during a thru-hike”
"Misconceptions about sexual activity among thru-hikers abound in some circles, especially in the fantasies of some younger male hikers and non-hiking types before they actually reach the Trail. Some seem to think the woods are full of libertines. Truth is, most thru-hikers exhibit and express very little desire for sexual activity during a thru-hike, at least in normal on-Trail situations (town rules are sometimes different for the more party-oriented thru-hikers). The standing joke about sex on the Trail is that, at the end of a strenuous day of long-distance hiking, everyone is too tired and too dirty to be interested. That is not to say that romance does not blossom and liaisons never happen, but usually a good campsite, tasty meal, and relaxed fellowship with Trail friends are more important and satisfying goals to the people who thru-hike. In practice, the thru-hiking community operates as a big family, with men and women thinking of each other primarily as brothers and sisters and fellow hikers rather than as potential sexual partners. Most thru-hikers value this sense of “family” above all other aspects of the Trail experience. Male thru-hikers, who usually outnumber female thru-hikers in most situations, should be extra careful with language and conversation so as not to make female hikers feel uncomfortable or threatened.
