It doesn't require anal sex, it requires prolonged skin-on-skin contact. The factor that makes gay men overrepresented among the current cases is likely to be the number of different sex partners, plus possibly a higher rate of detection because that community has been on high alert for a few days now.

The top comment was misleading. Of the number of people who practice anal sex, some of them are male. Of those, some are gay. Not all gay men practice anal sex.

Anal sex does not require a penis, and it does not imply bare sex organ contact. A better classifier would be "prostate stimulation" or "prostate orgasm", which all males can experiences and does not imply a particular sexuality.

My point is that there are far fewer power bottoms and gay men who want or enjoy another's penis in their anus than popular media suggests. Also, being gay doesn't imply indiscriminate sexual promiscuity. People who are that way will have sex with others regardless of their or their partners' sexes. Gay men are at higher risk of and when encountering these people because of smaller partner pools in any given area.
