Call it the Ellen DeGeneres Effect. The impact of the lesbian TV host and former “American Idol” judge on females aged 15 to 44 is now measurable: Women are going gay for sex more than men, and doing more of it now than a few years ago. It’s a scientific fact. So says the Atlanta-based Centers for Disease Control & Prevention. Armed with questions like this -- “Has another female ever performed oral sex on you?” and “Have you ever performed oral sex on another male, that is, stimulated his penis with your mouth?” -- researchers quizzed nearly 14,000 men and women across the U.S. for the National Survey of Family Growth. Don’t tell the conservatives that “family” has a decidedly gay bent to it. We culled through it all to find the best gay factoids: • Twice as many women went lesbian (12 percent) as did men (5.2 percent). • Women are apparently getting better at going gay: In the last survey, conducted in 2002, some 11.2 percent of women dabbled in the Sapphic. Men, on the other hand, were getting gay more in 2002 (6 percent) than in the recent survey (5.2 percent). So much for practice makes perfect. • There’s something to that adage that women go lesbian in college. Some 15.8 percent of women ages 20-24 – the highest of any age group – say they had same-sex behavior. The same goes for men. • For men, whites ages 20-24 did the gay (5.9 percent), the highest of any ethnic group. Black women ages 20-24 got freaky the most (16.7 percent). • Men doing the gay also got laid less frequently. In the last 12 months, some 11.7 percent of women reported any same-sex partners. For men, it was 4.3 percent. Of women with a same-sex fling, some 20.3 percent had four or more partners over their lifetime. Men? A paltry 5.1 percent. To sum up, men aren’t as gay whorish as we thought. Read the full study.
