"It is an important issue however and I
would hope that young people will not buy
into the idea that the ups and downs of
one's libido is not normal and that amping
it up would be the best choice. I would
imagine it would blow out your adrenals
eventually if you rutted like a rabbit
night after night."
-you're brilliant, ZB. I would also like to add that in my experience my life, in general, determines my libido. When things are going swimmingly and I'm having a lot of positive experiences/interactions with the world, have time to relax, smell the roses, etc, my libido is up. When caught up in the humdrum minutiae, overworked/stressed/tired, etc., libido meter is down.... Really not complicated...
