ADD Health interviewers rated the physical attractiveness of adolescent study participants and also asked them if they had ever been attracted to a member of the same sex. I'll categorize those who answered "no" as heterosexual, and those who answered "yes" as homosexual. Here are the means for physical attractiveness:
Physical attractiveness mean (N = 4,255, white sample)
Straight males 3.49
Gay males 3.44
Straight females 3.74
According to ADD Health data, homosexuals do not differ significantly from straights in terms of physical attractiveness. I had guessed that gay males would be more attractive, and lesbians less attractive.
