Do you believe people who were queer can just turn non queer

i guess if you just enjoy having sex with girls but emotionally u dont care who u date that can happen but if its the other way around i dont think so but idk tho I've never been a lebanese before

i think the world is too heteronormative for homosexual people to "pretend" to be homosexual or have a feeling that they're gay.
having said that alot of women can be "fake"bians and end up liking man even after saying she's a lesbian. i guess alot of women confuse their bisexuality + despising men with the "lack of attraction towards men". like, no. js bc you dont want to date a man or dont like how they behave, that got nothing to do with your capability of being attracted to men. ask yourself, if the would were ideal and all the males and females, they lived in harmony and there was no oppression, who would you feel attracted to? a heterosexual person should still be hetero in ideal world, a bi person would be bi, and a homosexual person would still be homosexual.
so yeah, and alot of men also suppress their attraction towards other men bc they find it "emasculating" to like men.
so in a society like present society, i think you can go straight to gay/bi not bc you became bi/gay, but you js realised you were infact bi/gay. not the other way round bc it's kind of expected of you to like opposite sex.

sexuality is fluid and things change as years go by, nothing is solid - but i feel if the person has actually had experience with for example the same sex (romantically and/or sexually) then i don't believe they're like... straight. they'd still be queer

That is possible and I believe it has happened to people around the world but I think they would then be called Bisexuals or Pansexuals due to their dating history. Religious wise they’d prefer to call themselves heterosexual but it would still be by definition bi or pan on paper. Idk though, not very educated in this topic
