>that's a much higher number than the incidence of gay and bisexual men in the overall population of the US (2-5%?) 1) A valid insight, but misdirected. The prevalence rate is still higher in heterosexuals. You'll find a common point in many medical texts that a lot of what happens in the homosexual community, disease wise, is due to how small it is. A smaller network makes it easier/faster for every node to get the message. >Gay and bisexual men and other men who have sex with men have the highest prevalences of gonorrhea, chlamydia, and early syphilis. 2) Right, in San Francisco. Not world wide. >Men who have anal sex with men (MSM) are more likely to get anal HPV than men who only have sex with women. 3) This isn't surprising, since homosexuals definitely have more anal sex than heterosexuals. You should compare this to general HPV rates. I am still awaiting support for your original claim about homosexual sex.
