So many interesting replies to this query. Thank you all for sharing!
As many of you have said, grooming practices are indeed personal, and people have the right do whatever it takes for them to feel comfortable or attractive in their own skin.
Some may indeed not feel pressure to remove body hair and "enjoy the ritual" of doing so. I am not suspicious of that sentiment itself, but of the industry that cultures it by manufacturing a problem in need of a solution (either products or services). While hair removal is an old custom, it wasn't something to which most women subjected the majority of their body's surface area.
Take underarm hair, for instance. It wasn't seen as disgusting roughly a century ago, when women began wearing sleeveless clothing. Rather, Gillette successfuly marketed their products as a "solution" to the "problem" of underarm.
Nowadays, women's beauty and fashion marketing seems less about encouraging overt self-flagellation than in promoting "indulgence," "decadence," "ritual," and "self-love"--treating yourself because you're worth it and deserve it. This is why I read Lisap's interpretation of hair removal--that's it's not a result of pressure, but a gratifying ritual--a bit suspiciously.
Something ceases to be a choice when your personal preferences attract unwanted attention, and when you feel that you need to remove hair in order to shake off that attention. Once you've branded a practice as undesirable, and once a critical mass adopts this practice, those that haven't yet adopted the practice feel enormous pressure to do so, regardless of whether that practice makes them feel more attractive.
