Oral sex--further information from sexual assault cases.

A survey was carried out of sexual assault cases submitted to the Metropolitan Police Forensic Science Laboratory during 1988 and 1989. There were 104 cases with male victims, and 1403 with females. In the all-male offences, fellatio was reported in 34%; nearly two-thirds of the acts were by the offender, one-third by the victim. In the offences on females, oral-genital acts were alleged in 22%, 78% of which were fellatio, and 22% cunnilingus. The majority of offenders were white. The few Afro-Caribbeans studied rarely performed oral sex on males or very young females.
