Your vaginal walls weaken
It seems that over the age of 50 or so, women risk not feeling any pleasure during sex if they don’t have intercourse regularly. Typically, the vaginal walls will get thin and weaken to the point of tearing while entering menopause, making sex extremely painful. The best way to prevent this from happening is to, well, keep doing the nasty well into retirement. Dr. Streicher told Reader’s Digest that thinning of the vaginal walls is due to lack of blood flow, which can be increased by sexual arousal and penetration.
