I really don't intend to dip back into this conversation, because Gregg is absolutely right--when it turns to values it gets personal, and I don't mean to do that. Madgeylou, you sound like a strong and very self-assured woman--I respect you and your choices, even though I can never in a million years see myself having the same "adventures" as you did. Then again, my background filters include a birds and bees talk with my mother that left me with the impression that I could get pregnant if I wore a short-sleeved shirt. So much for sex education.
