Trope Name Proposal

So we've got some established names for the common tropes of "harem series" (where the main character is a guy and has female love interests falling all over him left, right, and center), and "reverse harem series" (where the main character is a gal and has male love interests falling for her left, right, and center). But there are other options! I propose the following term names:

- Inverse Harem Series, for pure yuri harem series such as Strawberry Panic (I think?), where the main character is a gal and has lots of gals falling in love with her
- Double Reverse Harem Series, for a pure BL harem series such as Kyou Kara Maou, where the main character is a guy and has lots of guys falling in love with him
- Bisexual+ Harem Series, for a series like My Next Life as a Villainess: All Routes Lead to Doom, where the main character may be of any gender and has lots of characters of any gender falling in love with them

I'm not sure what to do with any series where the main character is agender or nonbinary or otherwise does not fit into a neat gender category, or if it changes at all depending on the gender(s) of the people interested in them. Bisexual+ Harem would fit regardless, but do NB x M and NB x W get different names? What about NB x NB? M x NB or W x NB? The term "Sideways Harem" comes to mind as a possibility, but would it be for all of those options, or just one? If just one, which one?

More thought and input are required.
