Here are three of my favorite "types" of sex:
1. Condomless sex. Duh.
2. Hotel sex. There's already that vacationy, removed-from-reality vibe making you feel all relaxed and horny, and best of all, there's no real clean-up involved. Daily maid service. I love hotels.
3. Morning sex. Because no matter how remotely bad anything else that happens the rest of the day is, you can still say, "Well at least I had sex today..."
