It's all because of the media. The media is to blame. It's definately because of the razor commercials, telling you to shave. And because guys see girls that shave their legs all the time, and they like seeing bare skin.
Technology makes it very easy for girls to shave now. Also: It was preferred that a girl, in history, was on the meatier side and now it's preferred that she be slim (as the media portrays). It's dependant on the times and the collaborative public opinion.
Well, in the earl 1900's it was deemed offensive for a woman to show her legs. Well, pretty much any flesh really. Times have changed, and now it's acceptable to go out bare legged.
Now then, for the science part.
Men are programmed biologically to go for youth. And if you look at the fashion industry for women, it's geared to make women look younger.
The make up you wear, it's to make your eyes look bigger than they are. Big eyes are a sign of youth. Lipstick, to make your lips look fuller. again another indicator of youth. Clear skin. well, you're getting the idea about foundation, concealer, and most of all "photoshop". :)
With regards to hairless legs, well, isn't that also a sign of youth. Likewise with armpit hair.
As for Brazillians. Well, I think that is pushing the jailbait look a little too far. But in essence, that is what the fashion industry is pushing women towards.
Heck, 30 years ago it didn't matter, and it still doesn't matter to me. I think it's odd-lookin and maybe a bit creepy. Certainly not attractive in any way. Oh well, the older I get, the younger everyone else is.
girls are beutiful. smooth, sexy, soft. the contour of a womens body, the small of your back, the little spot just barely below your belt line, its all sexy. men love to see that. long smooth sexy legs. there's a lot of places on a womens body that turn us on. being all hairy instead of smooth is definitely not sexy. soft skin for us to touch and kiss. :) if we wanted hairy we would be gay. yuck. a girl that smells good is sexy too.
There are two reasons that I can think of. Men are turned on visually, they like what they can see and the other reason is probably because more men now like to give their partner oral sex, its bettter without all the hair in their face.
The cat is out of the bag per se. Kind of like why do girls want to squirt or have multiple vaginal orgasms now or why do they want to try a big **** now. Because it looks, tastes, feels better! Thank god we're evolving our sexuality.
bombarding images every that convey shaved legs or arms are the essences of beauty and that is why to some extent there is an expectation guys and girls are shaved, and of course people have different preferences.
the media conditions people to like what they like
i was talking to my dad. he is in his early 50s and grew up in the 70s. he told me that back then boys thought it was sexy for girls to have VPL (visible panty lines), now that will get you made fun of because girls wear thongs now. they also had no problem with hairy arms and legs, now we are expected to be hairless. they didn't mind thick eyebrows either, now our eyebrows are expected to be shaped and thin
