Right, so she's bi, or has history's worst case of comphet (not totally implausible since she seems to only use men as sex objects and has presumably never actually loved anyone since she's a terrible person lol).
Of course it's a comedy manga so humor is being mined from the "I don't
want to fuck dozens of women but I guess I have no choice!" premise. But I mean, just stating it like that makes it clear this is a
"Why Do All These Homosexuals Keep Sucking My Cock?" thing lmao. She wouldn't have thought of this solution so quickly if she were actually straight.
