It's like it is unnatural to have hair.
Men are realising that women either look better without hair or just find hair to be a turn off...I know heaps of girls with hairy legs and guys like them aswell...maybe becaus its a new age full of wax, hair removal and many other things, people are influenced by friends, the tv and the media...in the olden days if you were hairy it didnt matter now days people usually prefer to be hair free because its easier to maintain and they can show of there assests better that way...
Being natural in that way actually refers to having hair that you are born with.
I think guys and girls love the feeling of hairless skin because its much smoother and just feels good.
Different ideas of beauty? (like how a size 0 has suddenly become the norm for actresses)
some people just don't like it.
