What is cleavage etiquette??? [I Want to Be Happy And Make Others Be Happy]

Imagine if you lived in a nudist camp. All around you would be people of all ages and genders in all kinds of activities. Very soon, like all nudists, you would cease to be affected by how bodies look and you'd start to pay more attention to the character of the person in the body.
This is the right etiquette for all people, irrespective of what they are wearing.

Now let's examine an opposite scenario. Let's say you're in a moderate Muslim culture where women are encouraged to dress modestly to show their devotion and surrender to Allah. The more modestly one dresses, the more modestly another must dress in order to express it relative to others and relative to the reactions of men to those few women who lag behind or choose to show more (even if they are ancient, deformed or crippled). If these keeps going, it ends up in a fundamentalist situation where women remain housebound, have no education and can go nowhere unless protected by a husband or close male relative. Woe betide the childless woman, female orphan or woman whose menfolk have died in war - for she cannot leave her home even to buy food.

The fact is men have libidos 14 times more potent than women's, and they must learn to control their urges no matter what women wear or don't wear. Otherwise we end up with a completely uncivilised society where women have few or no rights as human beings.

The feelings of lust come from inside you - not from what you see and react too. By the time you are 90, that same sight will be mildly enjoyable, like watching a flock of birds swirling in the sky. It's the hormones, not the woman's dress, that are at issue.
