Lol! I was wondering when comics would make an appearance!
I had a torrid but brief romance with a comic book artist when I was in my 20s. I still check him out on Deviant Art from time to time. Ahhh... memories... you'll have seen his work, according to your list.
I'll have to check out Sex at Dawn. I love books on human sexuality, and this looks like a good one. I have the Myth of Monogamy by Barash, who scathingly criticizes Sex at Dawn, so it will be interesting to read on that count, too. Do you plan to or have you read Sex at Dusk, an apparent rebuttal?
As for my "research", I am not certain I have enough responses yet... but I'll keep checking back!
