Male ducks will even do necrophilia with other males.

I get your point, but "most"? I've had 5 male dogs of my own over 40-ish years, and have known or met many, many others and I've never once had my leg humped.

Is there data to back that claim up?

Not arguing but also something I hadn't heard before. That there has been an absolutely massive increase in # of people identifying as bi and that that is the majority of LGBTQ+

Shakespeare too

The article pointed out that the same sex encounters were only high for females, idk if that’s that similar to humans.

There are lots of men who identify as straight but have sex with other men. So much so that medical literature often uses MSM as a category instead of gay. There’s an entire DL subculture among African American men.

Anywhere you go you can download Grindr and find oodles of guys who are in heterosexual marriages. The stigma is pretty strong, they probably can’t even internally recognize themselves as somewhat bisexual.

I mean, sexuality is a spectrum. It’s statistically unlikely that a large part of the population is at the exact borders of the spectrum and not even slightly in between.

Especially since afaik physical attraction is just a matter of appearance, and there’s very masculine women or very feminine men.
