The majority of trans women in the west are also androphiles it’s about 1/3 gay 1/3 straight 1/3 bi/pan.

The sexologists who've studied and worked with this population for many decades - Blanchard, Bailey, Lawrence, Cantor - say this is not so. Amongst adults, at least 75% of males who identify as trans are sexually attracted to females, including to the idea of themselves as female. Only a minority - 25% or less - are exclusively attracted to males. Most trans-identified males who claim to be bi/pan are not being truthful; they are known as pseudobisexuals.

Actual sexual response in humans exposed to potentially arousing stimuli is pretty easy to observe and measure coz it's physical: pupils dilate, hearts race, blood rushes to the genitals, blood pressure changes, skin temperature elevates, etc. Lots of people who claim to be bi, queer, pan or whatever coz they want to be fashionable, cool or politically correct do not show the same, a similar or any physical response to stimuli involving one or the other sex.

You have to take what trans people say with the proverbial grain of salt - with a whole shaker of salt, in fact. As Dr House always used to say, "everybody lies" - and this is especially true about intimate matters like sex. But people who base their entire sense of self on a lie and ascribe to an ideology that's a pack of lies are more likely than the rest of us to lie all the time about everything - especially if they think it will get them a leg up.
