Like red wine, some things become better with age. Even though you can't have the same sexual performance as at 20 years of age, or you can't make the same adventures -- "romantic," safe, that doesn't mean that with age you have to neglect this important aspect. Physical therapists explain in this article about “Prevention” that by age you can choose the best positions of sex.
All 30s
About 25% of pregnant women experience pain around their hips, and about 8% of them continue this problem 2 years after pregnancy in the United Kingdom, according to recent studies. Isa Herrera, a physical therapist in New York, explains that as a result, many women in their 30 ' s suffer pain when they experience certain sexual positions. To avoid this pain, Herrera recommends this position, writes Shire. “With hands and knees on the floor or on the bed, you keep the hip zone in neutral”, she explains.
Also, Herrera recommends a position “spooning”, either lie side by side with your partner, or face each other, or in the same direction. This is a very good experience experienced by young mothers, allowing a woman to control the speed and depth of penetration.
The 40s
Cases of Shiatic nerve pain, back pain tend to appear most after the age of 30 and 40, according to the American Academy of Orthopedic Surgery.
Both of the above positions are good for you, even according to Natalie Sidorkewickz, a University of Canada researcher who published a study on the subject in 2014. But if you feel more like Herrrera ,he recommends the “reversary courger”, or “flants”.
“Lie down, with your knees back up and back up slightly, with a pillow under your chest for support. This keeps your back neutral and will help you avoid pain”, Herrera says.
The 50s
During menopause, estrogen decline can make sex more painful. You may also be more likely to develop “polypsy of your hip”, which occurs when an organ like your bladder differs from your normal position and pushes against your vagina”, Harrera explains.
Try a sitting position where you're facing your partner and sit on his lap. Another alternative is that you lie on your back with a pillow under your ribs and your thighs open up to your hip to make it easier to penetrate.
