Emotional effects on desire and sex drive

Desire and sex drive make us act in a certain way when we are sexually aroused. Desire is not fixed, it changes over the years. Many things can reduce sexual desire, including:
tiredness
stress
mood changes (such as anxiety)
changes in contraception methods
feeling unhappy about our body
relationship problems
traumatic sexual experiences in the past
excessive drug or alcohol use
boredom with your sexual routine.
Desire for sex is greatly affected by our state of mind. If you are depressed, anxious or afraid about your cancer, its treatment or your relationship, you may find it more difficult to be sexually aroused.
