The article says about 4%, but if one really works at it, they come up with under 2%, or about 2.4% depending on how they measure it.
The trouble is that the one authentic survey, is the one ignored, back in 1994 and they did a study where they tried to get EVERYONE to answer, rather than just the loosy goosy types who want to talk about sex.
In that study they went back to people as many as 20 times, because they didn’t want to exclude them and what might turn out to be more conservative sexual lives, that is the study that found very little cheating going on by married couples.
So many of the sex surveys that have been used for generations, were self reporting surveys, from sources that attracted sexually loose readers.
Of that 2% of people who claim to be gay, we need to factor in those young people who have declared themselves gay because of brainwashing propaganda. Many young people now thing being gay is hip and trendy.
