Q & R: sexuality and marriage

Here's the Q:

Good morning, Brian! I've been an appreciative fan of your shared thoughts and insight. And when you needed to you have pointed to other equally wise and helpful scholars.

I was wondering if you could recommend an individual or resource that would give a Christian analysis on how sexuality has evolved in society, and how the church has responded historically. Any thoughts or help would be much appreciated. Thank you!

Here's the R:
For starters, I'd recommend Marriage: A History.
Lots of people are also talking about Sex at Dawn too. I haven't read it yet, but plan to, and several of my friends highly recommend it.
