Monofluid: attracted to one gender, the gender they are attracted changes.
Monofluid people can be multi-spec, but some may consider themselves just as mono, fluctuating between cetero, ma-, woma-, neu-, androgyne-, lesbian, gay, homo, hetero, straight,
etc. Different from
Single-Target, you can only feel attraction to one gender, but you still can feel attraction to more than one person.
