The nature of sexual assault on men and their help seeking following the assault was investigated. All men were seen at least once for face-to-face counseling at SURVIVORS, a counseling service for male victims. Data on 115 men were analyzed: 69 were assaulted while under age 16. Mean time from assault to contact with SURVIVORS was 16.4 years. 51 men (44%) were assaulted more than once. The assailant was known to the victim in all but 16 cases. 100 men (87%) were assaulted by at least one man, 7 (6%) by a man and a woman, and 8 (7%) by women. Forced anal penetration took place in 88. 27 men (23%) feared for their lives during the assault. 88 men (79%) sought no help and only 17 men (15%) reported to police. For victims assaulted under the age of 16, the assault was more likely to be their first sexual experience and they were more likely to delay contact with SURVIVORS for more than 17 years. They were also less likely to report to police. Victims assaulted by more than one person were more likely to have been assaulted by strangers, by women, and to have suffered physical harm. They were less likely to have experienced the assault as their first sexual experience.
