I've been thinking about this and here's what I think some more...
I don't think the 'men who want it are imagining children' etc argument washes too strongly. I also REALLY don't buy the overt patriarchy argument: I think it is more a 'devolved' patriarchy as Proles says, via ideological means.
I think there's probably an association with fear of sexuality going on, which of course would apply some people's paedophilic tendencies where they have them, but not all. Instead, I think the connections between hairlessness and porn are wrapped up in the culture of very young men. It is teenage boys, surely, who are most likely to pick up the messages about porn and celebrity women and then wrap that all up with their own emergent sexuality? I don't think they desire women-as-child, but they probably do find it just 'easier' to have hairless women, because of the whole hairy fear/vagina dentata thing... In other words it's their immature sexuality that is driving this?
And then, on top of that, there's a sort of normalisation of hairlessness for the whole female body. We old gimmers are starting thinking about this as pubic hair as part of the natural 'undercover' part of women's bodies, and those of us who are all of old, feminist and have partners who like stuff au naturel are 'labelling' pubic hair as private (ie sexual) and therefore - like many intimate body parts - as something allowed to be on show to partners.
Whereas young men and women (and some others!) are mostly starting with a 'desexualised' idea of pubic hair (even though we all know it is still sexual), in that they're framing it as general body hair.
Now THIS (bear with me
) is perhaps the bit that is influenced by the pornification of culture: the general extension of the naked body - and by default, it's need to be perfect, for which read hairless. So it seems just the same as depilating legs/arms etc.
What us ancient femmos are experiencing then is the cultural extension of a boundary between private and public, further into more intimate areas.
As well as everything else. Or summat.
