Brand New Sex With Same Old Spouse

Think Small. Little shifts can make for big changes in the feel of your sexual relationship, Saltz says. "Put your legs where you haven't put them before, face in a slightly different direction — even really small movements can spice things up."

Change Locale. Empty nesters might explore places beyond the bedroom where they've been more or less confined by children for the past zillion years. "I'm not advocating for something that will get you in actual trouble," says Saltz, "but moving the action to different rooms or the backyard can make sex feel a little naughty, which adds excitement."

Play a Game. Hillegass suggests role-playing games, such as meeting your spouse in the lobby of a hotel and pretending you're strangers, but if that feels a little hokey to you (as it does to me), you can give yourself more of a script by investing in a game like Love Lottery, which lets you scratch off tickets that suggest sexual favors.

Accessorize. Saltz advises adding "accoutrements that don't require a 20-year-old's blood flow to make things hot: whipped cream, a cute nightgown, a sexy movie, a toy."  Saltz, who made a recent video on keeping sex in your life when you have rheumatoid arthritis, says: "Adding things like pillows in strategic places can be exciting if they prop up sexy parts but can also make you more comfortable and make your partner better able to stimulate you."
