OK
I personally think that at the stage of puberty, as the hormones are boiling like a kettle on the hob, the mind thinks that the opposite sex is the model of perfection. At 14 neither males nor females have a great deal of visible hair, but the concept of the invisible hair (in the golden triangle) takes on mythical status.
So that is the image that we all try to maintain and copy until we have grown up enough to want to be individuals and make personal statements. The first time I saw a lady with arm hair I was agog, but then discovered that this was perfectly normal in Germany and many parts of France.
As a slight variation of the theme, it was interesting to hear the baying of the pack (of women, all ages) when Andre Agassi removed his shirt at Wimbledon to reveal that he was now sporting a smooth upper body. OK it did help that he had pecs like cupboard doors.
So, the flip side. There you are at the hotel pool. Enter that bloke. The one with the amazing rug. Not just a welcome mat at the front door, but a complete Batman cape, winter grade, on his back. It's enough to make me want to pluck off on my own back.
