I'm single via divorce. I share my house with a man I once dated (and had sex with)--though over 15 years ago we stopped that and became best friends. He's not who I divorced. If this paragraph stresses you out, don't write me.
I wish I were having more (well, any) sex with a person other than myself, but to enjoy that, I have a perverse need to feel connected to and trust the other person--wait, I also have a vagina--is that redundant?
