>>62660891I don't think Pomu ever said she was bi, it's just heavily implied by the fact that she collects tons of bishojo figures and loli doujins and splurges at maid cafes and idol shows, but at the same time is down bad for bara-type males like Snake.
The one time Pomu brought up her ex-girlfriend (over 2.5 years ago), she said it was a bad experience she never wants to have again. So for her, it's probably more like she's sexually attracted to girls, but doesn't want to get into a serious relationship with one anymore, after the bad experience she had. (I'm sure I don't need to pull up the stats on lesbian domestic violence)
