pssst. I bought "Sex at Dawn." I don't intend to read it (I don't read, I tried to today... meh, not happening)... just leave it lying around.
I intend to lend it too my co-workers actually. We talked about it today at work. They all agreed that we were not meant to be monogamous for life, but serial monogamists maybe. I will see what a bunch of die heart monogamists say.
