Sex gives a lift to both your mental and physical health: "Did you know that semen acts as an antidepressant? Yes, semen helps fight the blues. A study at the State University of New York in Albany found that females who had sex without condoms had fewer signs of depression than women who used condoms or abstained from sex. That’s because semen enters the bloodstream and fights to counteract depressive symptoms. Remember, it’s always best to practice safe sex. But if you’re battling the blues and you’re in a healthy monogamous relationship, don’t hesitate to occasionally send your man’s 'lil’ soldiers' to war."
