Why does my vagina shut down after 8 p.m. and other sex timing questions in this week's column

My Let's Get It On sex column this week is called It's Sex O'Clock, time for a weekend romp and is about how I balance being part of a couple where one person wants sex at different times of day than another person, and how other people do as well, along with some suggestions on compromises. If you like it, I'd love it if you'd pass it on, comment, mention it on Twitter and/or like it at the top! I have tons of ideas for future columns and hope to keep writing it for a long time, but know much is riding on how many people are reading these first columns. That being said, I welcome ideas for future columns, nothing is off limits. Email me at rachelkb at gmail.com with "Column" in the subject line and your ideas. Thanks for reading!
