Regardless of what the tags say, a male gets turned into a newhalf is what the artist intended this to be. Tag responsibly!

"A character's body changes gender from their usual one. May invoke transformation if it is shown as a sequence and not a sudden change."
The description does not say that the character's genitalia need to be transformed.
There are many other similar works that are also tagged as gender bender.
Here's several by papermania:

I'm sorry if you're upset by how this tag is used, but it has been used in this context many times before. Please take this into consideration.

Edit: The gallery is properly tagged now so downvote me all you want.

"Note: Should not be confused with body swap or crossdressing. A female becoming a futanari does not count (but may qualify for dick growth)."

This would normally be crossdressing or sissyfication. But since he grew breasts it can probably count.

@sensualoi
sissyfication isn't a tag, it's feminization, which is more than just crossdressing but not necessarily about humiliation like sissyification is.

I don't understand how to use the wiki (and too lazy to start using it anyway) but feminization shouldn't be confused with genderbending as well. Since he retains the main sexual characteristics of men but gains the breasts (secondary sexual characteristic) this should count as a feminized man.

tl;dr - Someone add to wiki to not confuse feminzation with gender bender, kthanksbye.

@Aran1
shemale tag belongs under female namespace, so transformation from male to shemale should be valid use of gender_bender tag.

At least, that's how I understand it.
