Excellent question and I have to agree.
When I first got married in the early sixties, there was a moral decree of society for women to cover up.
When my wife first went to have a works medical she would not tell me a thing about what happen because "nice women do not do that", but you could tell it had an effect on her. When I was posted abroad, when she became pregnant, I went alone to the exams to support her. Like in the UK I expected to wait outside in the waiting room, but her doctor told me to come in. Being in Europe the exam was done without gown or covering and it was the first time I had really seen her. It could have been that I was watching, but she was so sexually charged stripping off in front of the dr.
I have often thought it was sociality or tradition saying that men should not see you naked, but she wanted to break the moral bonds and by going to the dr she was making nudity "morally legal"
It really changed her, she keep the light on when we had sex, and expected me to go to all her pre/post natal exams
My daughters on the other hand, found no excitement in going to the doctors at all and just treated in as a chore. Their attitude was that they went at least topless on beaches so what was so special about stripping off at the dr.
We have just had our 2 days of summer so women are wearing strapless dresses and flip flops. We were amazed at the amount of women with tats. Not just discreet ones, but covering most of their back, and it is not limited to the young, a lot of grannies are being tattooed. Something I would have never had seen in the 60's
