Dr. Sawyer: Absolutely. Despite sex being touted as a stress reducer and a nice way to relax, too much stress can definitely kill your sex drive. In previous answers I’ve already discussed the complexity of a woman’s sexual response, and likened it to a computer motherboard, vulnerable to many external influences, like stress and anxiety. Although men’s sex drives tend to be less inhibited by extraneous problems, at a very fundamental physiological level, the male erection is nothing more than a spinal reflex that kicks in a vascular response, and so stress and anxiety, often at the subconscious level, can directly interfere with a man’s ability to get busy, leading to much amazement, embarrassment and huge disappointment. Being stressed out is definitely not a positive in the world of sex.
