Terms like Heteroflexible, homoflexible, pansexual, omnisexual, mostly straight, mostly gay, etc. are just other terms or synonyms for being bisexual, and they are usually used by people who have a lot of internalized biphobia and who will use any term they can to avoid actually coming out as bisexual, and that's not falling back on labels/terms, or does not mean that calling these people bisexual means that you do not understand human sexuality, etc.
But I have read posts of yours where you seem to lust and worship hetero/straight men and the unobtainable fantasy of having sex with them the way some gay men need this sex fantasy.
