The debate about how sex affects sportspersons has been there for a very long time, but it is its reverse which is somehow more applicable. Research has shown that regularly engaging in sports or other physical activities such as exercising can have some really positive effects on your sex life. This has got to do mostly with improved metabolic activity in the cells from the increased motion and exercise.
Research suggests that engaging in exercise, sports and other physical activities result in an increase in flexibility and agility among people, thus aiding sexual prowess and performance. Also, it boosts levels of self-confidence, thus allowing you to believe that you are sexually desirable, (due to increased levels of fitness and toned musculature) which in turn also positively affects sexual capability- in providing higher levels of satisfaction to your partners. Apart from these, there are several other factors of sexuality that are also improved due to engaging in sports or exercise, like:
Decreased risks of Erectile Dysfunction (ED): One of the most essential benefits of engaging in sports and exercise is that it lowers the risk of erectile dysfunction in men, due to an increased level of blood flow into your penis as a result of widening of the arteries. In this regard, research also suggests that you don't necessarily need to be overly fit or sporting to reduce chances of ED - even a brisk half hour walk works wonders.
Improved quality of semen: Research has found that if you exercise or are engaged in some rigorous sporting activity for at least 15 hours per week, you will have higher sperm counts than your inactive counterparts.
Increased libido: High levels of exercise pumps up testosterone levels in men and estrogen levels in women, which leads to better muscle growth and an increased sex drive in both sex.
Increased chances of achieving orgasm in women: If you work out frequently, then the process of arousal works quicker for you and chances of orgasm is faster and with higher intensity, it gets increased exponentially.
Heightened sensitivity: In women, the clitoris contains over 8000 nerve endings, which makes it very sensitive to stimulation, and increases arousal exponentially. Increased physical activity heightens the effect of this stimulus and makes sexual stimulation much more pleasurable.
