OakAsFan likes to make up his own statistics. The definite sex study was published in 1994 as "The Social Organization of Sexuality" in the academic press and "Sex in America: A Definitive Survey," both by Edward Laumann, John Gagnon, Robert Michael and Stuart Michaels, and published by the University of Chicago Press. Based on the most extensive surveys ever done, they found that 1.4% of females identified as lesbian or bisexual and 2.8% of males identified as gay or bisexual. The prior figure bandied around was 10%. There has never, I repeat NEVER been a claim by any group for a 25% figure. That's Fantasyland insanity.

It should be noted that a British survey found 6.1% for males and 3.4% for females in the UK, indicating regional differences, but neither approaches 10% and none come close to 1 in 4.
