Keep Yaw Hands to Yawself: A Guide to Interacting with the Ultra-Orthodox Girl.
A quick take on the laws of hands-off between man and unrelated woman and the laws of Tzniyus mirror private property concepts. Private Property doesn’t mean no one uses the property. It means it is off-limits to those who aren’t invited in. A woman’s body is her own, to be off-limits to public trespass. So, hands off, buddy.
Some great reading material on the subject:
My all time favorite — The Antidote: Human Sexuality in a Torah Perspective by Rabbi Shrage Silverstein
Doesn’t Anyone Blush Anymore by Rabbi Manis Friedman
The Magic Touch by Gila Manolson (Gila Manolson can be heard on audio at http://www.simpletoremember.com a site I highly recommend for the thinking Jew to find inspiration and amazing lectures.)
