-sexual performance anxiety (often related to sexual dysfunctions)
-a preference for porn and masturbation over partner sex
-physical problems like diabetes, high blood pressure, obesity
-interpersonal problems between the couple
-stress
-prescription medications that kill libido
-loss of libido because of old age
-low testosterone levels
