Professor Gordon Gallup of the State University of New York in Albany has written a report alleging that women who have sex without a condom receive a natural high from sex: because male semen acts as an antidepressant.
Many women have claimed to feel a difference after having sex without a condom. "The whole next day you really feel much better. There's definitely a difference," one fashion designer says.
Semen contains many hormones and chemicals, some of which are absorbed into a woman's bloodstream during sex. After polling hundreds of women for how sex influences depression, he has found strong (if not conclusive) evidence to support his theory.
