Sex is a natural part of humanity and is incredibly good for you.  There are plenty of social reasons why sex is frowned upon but as a doctor I can assure you that sex has WAY MORE upside than downside.  Physically sex lowers blood pressure, reduce the risk of heart attack and dilates your blood vessels.  It reduces the risk of prostate cancer, strengthens a woman's pelvic floor reducing incontinence while driving estrogen levels to a new level.  This is so good for you.  Sex reboots your immune system and overall makes you a physically healthier person.

Emotionally, sex improves sleep while increasing connection between 2 people.  It's calming and positively affects mood.  It reduces most of the negative effects of stress while increasing the deepness of the relationship.  Don't fret if you're not in a relationship; a good solo mission will do just fine.  SEX is wonderful for all things human as long it's exercised with respect and responsibility.  Is it time to Shag?  It's up to you.
