1. It doesn't come easy Hot sex isn't just for club-hopping twenty-somethings. Men and women over 40 can increase the quantity and quality of their trysts by making a few changes to different aspects of their lives.Sexual desire doesn't diminish once we hit our 40s, but other things do, such as our overall health and lifestyle. To get the frisky sex back in our lives, you have to work at it. Learn new sexual positions, or make love in the morning when you have more energy.2. Marriage can be sexy Statistics show that married couples and people over 40 in monogamous relationships have more sex and better sex than most single folks over 40. Don't fret if you're divorced or unattached. Get your social life on track and met more people.Take advantage of dating services for people over 40. Get out after work and meet potential mates. If you're going through a rough patch and can't find a partner, masturbate. It will keep the vaginal wall flexible and sexual juices flowing in females, and prevent males from becoming too frustrated.3. Learn about natural sex boosters Some natural supplements do work. Look for ones that contain ginger, ginseng and the Chinese herb dong quai. Eat foods that increase strength and energy levels, like salmon, steak and cottage cheese.Salmon, which contains Omega 3 fatty acids, revs up blood flow which fights impotence in men and increases libido in women. Adding spices like curry, cayenne pepper and horseradish to foods perks up your libido, too. If natural libido boosters fail, there's always Viagra for men and doctors are currently working on libido and menopausal medications for women.4. Exercise for better sex If you're overweight or your joints are a little sluggish, your sex life will slow down as well. If you feel better during the day, you'll have more energy for sex at night. Jog, play tennis, do yoga or engage in other sports and exercise routines. Get in touch with your body with an occasional massage at the health club or spa.5. Schedule a tryst With all the responsibilities of work, family and society and the natural aches and pains of aging, people over 40 may experience reduced sex drive from the stress and strain of everyday life. Although the constant, unbridled college passion may be a pipe dream for most, scheduling romantic dinners or massages with your partner can pep up your sex life.Get a babysitter or Grandma and Grandpa to watch the kids and make a "date" to go to a nice hotel for the weekend. These scheduled interludes are a sure way to fire up sex after 40.
