So complicated...

Yes

It's not that deep

no, because you can't read minds and a lot of them a made up idiocy.

Why would you tag pronouns to begin with?

Like posting a trans and using the tags xer/xim?

I don't mean pronouns, like, whenever I use the "1girl" or "1boy" tags, I'm referring to that person's sex.

well, yes, you should post the persons sex, because it makes searching for porn easier. But since you can't read minds and a lot of the new genders are made up idiocy (see my prior statement) just tag their actual sex.
See my porn for example. Some people think, just because I like to dress up for you lot, that I identify as a girl. But, surprise surprise: I was born with a dick (small one, yes, but still a dick), X and Y chromosomes and every other biological marker for "male" and thus I am: MALE. Surprising someone should use obvious and very visible biological and actual criteria to guess what sex/gender I have.

OH I see, I guess tagging following the conventional of:

if have a dick = male/boy
if have a cunt = female/girl

and prov adding something like trans and similar. The idea is to tag what you see, not what they are or have.

Like tagging big ass to a photo of a girl that we know have a big ass but in the picture the ass isn't showing.
