Plausible theory: Gays have a mutation on the X chromosome that women also get (of course) that makes them more attracted to men than they would be otherwise. In women, this is advantageous, and a study showed women who are relatives of homosexuals have 1.3x the number of kids on average. For men, it is deleterious but women can carry the gene onward so it doesn't disappear. Gay men do sometimes reproduce and surrogacy will only increase that number.
I'm not exactly sure how womb environment and sibling order plays into this but I was wondering if someone who has read more recent research than I could update me on what researchers have been saying in terms of the genetic or otherwise causes of homosexuality.

Probably just different causes. Liking the same sex is a huge category so it only makes sense that there's no one cause to it. Genetics, hormonal anomalies both in the womb and in puberty, personal experience, etc.

Well surely the research has gotten a bit more specific into those?

>gays like men
>therefore they are women
makes sense anon

I didn't say that?

There IS proof that androphiles are feminine and gynephiles are masculine, regardless of their sex.

Women also get this same mutation because they also have an x chromosome. It was worded awkwardly perhaps but you got the point.

Extreme homosexuals = non AGP tranny.

>but seriously this implies that gays are less feminine mtfs and that seems very unlikely to me.

Fuck you and fuck your pseudoscience. Pretty much every study shows ~15-25% of androphilic MTFs were "AGP" at some point and that only 75% of gynephilic MTFs were "AGP" at some point. On the other hand there is a great deal of research showing that the brains of transsexuals, regardless of orientation, are sexually dimorphically different from those of cis individuals of their natal sex.
