This comparison is not exact: Laumann found that less than 5 percent of men said they'd had a same-sex sexual experience since age 18. Kinsey's famous finding was that 10 percent of men were primarily homosexual between the ages of 16 and 55. But when Kinsey asked men whether they'd had at least one same-sex experience in which they'd reached orgasm, a whopping 37 percent said yes. That means that the differences between Laumann's and Kinsey's findings on homosexuality may actually be bigger than they first appear.
