Hi, my English is bad, but I will try.
I uploaded most of these works with Bridget, so I feel responsible for explaining why certain tags are put.
post #6180188 and post #6251287 are covers for yaoi manga.
It's a product to sell to a specific audience has nothing to do with futanari
post #6993898 has the appropriate title and tags
ブリジットくん可愛い…!男の娘描くの楽しかったです
Bridget-kun is cute..! It was fun to draw a otoko no ko
It's just fetish art, not sure if it's even breasts, it's probably just the way it's portrayed..It's yaoi art.
The post #7108352 literally in the post has the tag otoko no ko, the comment also indicates a male.
The post on pixiv is also male

I'm thinking of uploading in the future
https://www.pixiv.net/en/artworks/117127998.
And I will tag it with the same tags as the author.
Art hakusyokuto
All his works with Bridget otoko no ko.Recently, the author started drawing femboys with breasts.
Examples are not Bridget
post #7174321 , post #7071644
He also has artwork with pronounced waist and butt examples post #6510745 and post #7174411
The artwork of this artist has a fetish character and has nothing to do with futanari and gendersweep, these works are intended for a specific audience..with specific tastes.
The author puts suitable comments and tags.
For example, post #7519330
Tagged 男の娘 and オス堕ち.
Explanation for the second tag

And also sold accordingly

I repeat this is fetish art otoko no ko, not futanari or genderswap!
Why do I pay so much attention to pixiv?
The works on pixiv are organized in a structure of extensive tags, which are the basis of the website.
Art authors put tags and want their work to be found through them
I don't see a problem with tagging these posts as otoko no ko and male with breast, given that such art is already on danboru and is intended for the same audience.
Now let me explain a situation that does not affect these posts, but may arise in the future and generally occurs quite often.
For example post #6422299
The original post has the tags
男の娘 otokonoko
ふたなり futanari
This post used to be tagged man with breasts,but I noticed it disappeared and now it's futanari
There are many examples like this and may still have tags:
女装男子
異性装
女装
女装子
And also トランスジェンダー
Most of the time, this kind of art is labeled futanari because of the presence of large breasts,but sometimes there are exceptions.
I think there will be a Bridget post with some controversial tags in the future.
I've uploaded many Brigitte posts that are tagged futanari, transgender flag or genderswap.And I don't think I've mislabeled these posts.
After all, pixiv is not Twitter and it's clear what the author wanted to portray.
