is a sexual behavior, or a sexual act forced upon a woman, man, or child without their consent. Sexual abuse includes abuse by another man, woman, or child. Sexual abuse in childhood may result in problems of depression and low self-esteem, as well as in sexual difficulties, either avoidance of sexual contact or, on the other hand, promiscuity or prostitution. Sexual abuse in children is regarded by the World Health Organization (WHO) as one of the major public health problems.
