^‡For each partner type, participants were asked “In the last 6 months, with how many men did you put penis in the man’s rectum (with or without a condom)?” For men who indicated that they had had insertive anal intercourse within the past 6 months, the following question was asked: "With how many of these men did you use your own saliva as a lubricant (“lube”)?
