The Mayo Clinic suggests the following tips for sexual health and happiness, particularly for those seeking to improve sex as they age.
Expand your definition of sex For example, touch can be a good alternative to intercourse, or try a sensual massage, masturbation or oral sex.
Communicate with your partner Discuss any changes you're going through, and ask your partner about their needs.
Make changes to your routine Change the time of day when you have sex or try a new position. Make time to set the stage for romance, such as an expensive dinner.
Manage your expectations If you didn't have sex often in your early years, don't expect to have more as you get older.
Take care of yourself A healthy diet and regular exercise not only keep your body tuned, but keep you ready for sex at any age.
