Hmm...the only reason people (not just men) are obsessed with them is because they're such a taboo. 100 years ago it was considered indecent for a woman to show her ankle...with more and more exposure, that indecency became absolete...now no one gives a fuck about ankles. 30 years ago you wouldn't have seen the slightest bit of clevage on public television...now if everything except the nipple is uncovered, people don't really care all that much...It seems it's like anything in the world...create a rarity, and people get obsessed with it.
