Sixty-eight homosexually active men attending an STD clinic were questioned to ascertain the percentage of the time they did not use condoms during anal intercourse, and the reasons for this. Data indicated that the reasons most commonly given were being in a steady relationship (32.8%), being unprepared (19.4%), couldn't be bothered (19.4%), use of alcohol or drugs (7.5%), being bisexual (4.5%), attractiveness of partner or partner attitude toward sex, and knowing the partner (3% each). These data suggest that both trust and situational variables are barriers to consistent condom use in homosexually active men.
