Although one of the characters is clearly bisexual, I don't see a corresponding tag. Please fix this.
The whole "couldn't go all the way with men" thing suggests otherwise.
Okay, but she had physical contact with many men; that should be somehow indicated in the tags. I, for example, have a mental disorder, and a scene like the one on page 15 pains me a lot.
Note that tags have specific usage definitions here that may differ from your own personal ideas of them. To wit, bisexual is:
“Meant to describe content, not strictly identity. Should be used in cases where a character's sexuality is especially relevant to the plot or character themselves. One-off lines do not count.”
So Kuroiwa simply mentioning offhand that she has dated men is not a statement of identity, nor is it particularly relevant to the situation at hand except in a “why did I never care about sex/romance before?” kind of way.
All that said, it seems someone found and applied one of the randomly-perfectly-appropriate hyperspecific old tags just for you. :)
