Sex in the early stages of a relationship is undoubtedly exciting.
You're still getting accustomed to each other's bodies, feelings things out — quite literally — to get a grasp on what'll get your partner's toes curling. Everything is shiny and new, and each time your clothes come off, there's a good chance you'll uncover something about your partner's sexual preferences that you never knew before.
It's as the relationship goes on that things can begin to feel a little mundane. You've been having sex with this person for so long that you know what to expect. It's that comfortability level that has you getting in, getting off, and getting out because you can.
Sometimes, the sex can feel hot and passionate, and other times, you're letting out forced grunts, eager to roll over and get the hell to sleep.
