I don't agree with point one because there are very practical reasons for cutting your fingernails and hair, though of course hair styles and nails are subject to fashion whims - they are on show. I don't think the comparison with body hair stands up at all.
I'm not sure I really understand the point you're making in point two - do people get suntans for their partner? Personally I think all of those things should be done for yourself, though equally they are also subject to the whims of fashion - I was a deadly pale teen when deep suntans were the thing and yes, I was ribbed for that.
Other people have the right to say what they do and don't find attractive - and we have the right to take as much or as little notice of that as we choose.
From your previous post, I find your description of a self conscious teen not following the crowd because they knew they'd never fit it a little unbelievable. I think you've got to have a lot of self esteem and confidence to shrug your shoulders, think 'I'll never fit in so why bother' and go your own way. Absolute hats off to those teens who can and do do that.
Anything to do with the effect porn is having on our children is surely to be debated, and yes, I do still think that porn is the driver behind so many young people removing all their hair, just as it seems to be the driver behind a lot of other pretty unpleasant things our teens have to navigate. Poor mental health among girls is at a record high. The number of girls seeking to transition is also through the roof. Puberty for girls has always been pretty crap but what with social media, porn available on everyone's phone, everything one does being so bloody public - bad times.
Back in the day you might be judged on your hair style or clothes. Back then, whatever you did with your pubes was your business alone, quite rightly. Now young women are being judged on their pubic hair, something that should be kept totally personal.
I make no judgement on any woman choosing the remove their body hair, even if I don't think their reasoning always entirely stands up - none of my business. I question how many younger women especially are making a truly free choice to do that, and I very much judge what might be driving that. I question and judge that in exactly the same way I question and judge other societal pressures that force young people to go against what they really want to do or be.
And I certainly don't pretend that it isn't happening. I think that perhaps older women who have done this for years, outside of the influence of porn, are probably feeling rather judged and attacked, but the fact that some people can't separate their own individual choices from an examination of a change of behaviour for women as a whole shouldn't stop us from asking awkward questions.
It's an interesting debate and I've enjoyed reading your posts. I have certainly changed my stance on this from when I first read threads about it a few years back.
