Never got the shower thing. It is so simple to take a sponge bath and keep clean anywhere when traveling, be it 20 miles from the road or in a cheap hotel room with just a sink.
This whole discussion isn't so much a male/female thing as it is personal priorities. Either you want to be out in the wilderness and are willing to make compromises or changes from city life, or you don't. You trade the bugs, dirt, sleeping accommodations, food, etc for the solitude, peace, views, flora and fauna. Like all travel, seeing new places and vistas is the goal. If you don't buy that, you will may be miserable.
I'm not much of an athlete, but I'll trade the exertion for the positives (and knowing that is is good for me). There IS a sense of accomplishment in dragging yourself up 2500' of switchbacks on a hot summer day. The alpine lake in a dramatic cirque is a fine reward. Seeing an osprey snag a trout is desert.
Those who do best are willing to try new things and look at life as a grand experiment. If it doesn't work, fine, but you get rewards when you try something new and you step outside your comfort zone. What puzzles me is when I run into people of any gender who won't step out of the zone a bit. I'm sure there is a Briggs Myers personality type that goes with it.
We sat at a breakfast table in a small Parisian hotel having a feast of fresh bread, butter, jam, pots of coffee and hot chocolate and fresh orange juice. One of the couple sitting next to us whined about not being able to get bacon and eggs. All I could think was, why didn't he stay home? He would really be in trouble in a village in Laos or the Andes! Want to go backpacking with that attitude? NOT!
Do something every day that scares you a little!
