Some initial searching (doing psych medline searches doesn't come easily to me), I found some related stuff (not all on men, I was trying to find individual papers and use the related papers _link_ to get more focused literature). The most recent review doesn't give numbers in the abstract but claims to examine prevalance of childhood sexual abuse in gay men.
http://www.ncbi.nlm.nih.gov:80/entrez/query.fcgi?db=PubMed&cmd=Displa... The few papers that gave numbers reported percentages ranging from 20-35% in terms of the prevalence of childhood sexual abuse in gay men. Unfortunately, a lot of the papers are also looking at prevalence of risky behaviors so it may be a subset of a subset. So Dr. Drew's claims of universality may be overstated, or reflect the fact that Southern California is fucked up, or inherent problems with surveys or what have you. IAE, there's a much higher prevalance of childhood sexual abuse (typically by older men involving coercion or force) in gay men than in other groups. Not conclusive but certainly suggestive. A couple of the abstracts below and I'll keep looking Lyle's ghost **** 1: Child Abuse Negl 1992 Nov-Dec;16(6):855-64 Self-reported childhood and adolescent sexual abuse among adult homosexual bisexual men. Doll LS, Joy D, Bartholow BN, Harrison JS, Bolan G, Douglas JM, Saltzman LE, Moss PM, Delgado W. Division of HIV/AIDS, Centers for Disease Control, Atlanta, GA. From May 1989 through April 1990, 1,001 adult homosexual and bisexual men attending sexually transmitted disease clinics were interviewed regarding potentially abusive sexual contacts during childhood and adolescence. Thirty-seven percent of participants reported they had been encouraged or forced to have sexual contact before age 19 with an older or more powerful partner; 94% occurred with men. Median age of the participant at first contact was 10; median age difference between partners was 11 years. Fifty-one percent involved use of force; 33% involved anal sex. Black and Hispanic men were more likely than white men to report such sexual contact. Using developmentally-_base_d criteria to define sexual abuse, 93% of participants reporting sexual contact with an older or more powerful partner were classified as sexually abused. Our data suggest the risk of sexual abuse may be high among some male youth and increased attention should be devoted to prevention as well as early identification and treatment.

Lenderking WR, Wold C, Mayer KH, Goldstein R, Losina E, Seage GR 3rd. Department of Biostatistics, Harvard School of Public Health, Boston, MA, USA. Of 327 homosexual and bisexual men participating in an ongoing cohort study pertaining to risk factors for HIV infection who completed a survey regarding history of sexual abuse, 116 (35.5%) reported being sexually abused as children. Those abused were more likely to have more lifetime male partners, to report more childhood stress, to have lied in the past in order to have sex, and to have had unprotected receptive anal intercourse in the past 6 months (odds ratio 2.13; 95% confidence interval 1.15-3.95). Sexual abuse remained a significant predictor of unprotected receptive anal intercourse in a logistic model adjusting for potential confounding variables. PMID: 9127231 [PubMed - indexed for MEDLINE]
