It's a cliche, but

Cross-country skiing is as much fun as sex, and most people look as bad doing it.

Like sex, cross-country skiing causes a lot of bodily secretions to flow. They just mostly come out of different openings. So cross-country skiers perform their exertions coated with glistening moisture. They grunt. They sweat. They breathe hard. Afterward they're suffused with a glow of satisfaction, or perhaps frustrated by an inadequate performance. Usually you feel better than when you started.

You'll see occasional beautiful people and professionally competent-looking performers. You have to wonder if it feels as good to those show ponies, or if it's just a job. Some of them do seem to know arcane secrets of ecstasy beyond the powers of the average grunt. Is it worth it? What if it isn't really any better, just strenuously kinkier? You never know until you try. But you increase the odds of hurting yourself when you try to get to those advanced levels. You could drown in the hot tub or fall from the trapeze or asphyxiate because you didn't get the scarf untied fast enough-- I mean you could hit a tree on the way down a steep trail you weren't ready for, or pull a muscle.

Go for it. Have fun. I, for one, won't be watching too closely.
