MALE bisexuality does not exist, psychologists in the US have claimed.

A new study concludes that the large majority of men purporting to be bisexual are actually gay, while the rest are more likely to be heterosexual.

Senior author Michael Bailey, from Northwestern University in Chicago, said: "Bisexual male behaviour certainly exists, but the study suggests that a bisexual orientation, an actual sexual preference for both men and women, does not exist in men. If such men exist, they are certainly very rare and we didn't find them."

Researchers recruited 101 young adult men, 33 identifying themselves as bisexual, 30 straight and 38 homosexual.

They were questioned at length about their sexuality before being seated alone in a laboratory to watch erotic films while their arousal levels were monitored by a sensor.

Gay men were aroused by images of men, while heterosexual men were aroused by women. But psychologists said those claiming to be bisexual were only aroused by one or the other - 75 per cent by men and the rest by women.

Dr Bailey said some men claim to be bisexual as it is easier than admitting to being gay, while others might consider it some kind of achievement and be proud to swing both ways.

This is probably a topic almost as old as time, but what do Forum members think.

Factor in the lady-boys into the equation here in Thailand ...

I have always been of the opinion that nobody is 100% gay or 100% straight but somewhere between the two extremes.

Comments anybody?

An occasional fling, one way or the other, is not a "sexual preferrence" which is what the phycologists are talking about here.

My test for the "claimed" bisexual is to have him imagine the most attractive member of each sex naked in front of him and then make him choose one or the other for his sexual satisfaction.

This method predated the test in the OP which sounds vaalid as the sexual response monitored by the sensors are accurte readings of response, perhaps like a lie detector.

Sure you could fool the machine with practice and some might want to due to societal pressure, but chances are they are few.

I have always believed what the OP test seems to confirm, you one or the other or confused.

This research basically shows what many have already known--most bisexual men are just closet cases.

I am pretty sure that methodology is probably accurate. I don't know what sensors they use now, but some years back it was the plethismograph (spelling)., which was a small wire around the penis and it measured very slight changes in the arousal level. This makes the sensors hard to outsmart, since it can detect slight arousal levels.

Adolescents are hard to test since they are easily aroused. They frequently have a sexual response to non-sexual stimuli such as a picture of a flock of birds or flowers.

These tests were quite successful in identifying pedophiles. Believe it or not some child molesters are not true pedophiles and their arousal level to pictures of children is minimal. (They are usually classified as regressed pedophiles and the molestation is in response to current trauma in their life that makes them return to an earlier age--emotionally and thus they may seek sexual gratification with younger girls, but not young children and not boys).

Since the sample was small (but significant), one shouldn't rule out bisexuality as non existent, but rare.
