Yea, I reject the naming convention here entirely.

Sexuality is a spectrum. And, like you are insinuating, where someone falls on that spectrum can change with time (sorry pray-away-gay folks, this can't be forced = simply put, we like what we like).

Where you land on that spectrum, NO ONE should give a shit about. Focus on your own genitals and the genitals you are trying to please and the extent of your total genital thinking should end there.

Sometimes there are lifetimes of experiences to explore in sexuality, for some people, it's cut and dry. All the options in between are just as ok as well. With that context I don't see justification for the impoliteness of not minding my own fucking business
