I can’t speak for them because I’m a woman and nothing like that has ever been expressed to me. But I still don’t think that would make a person gay. For instance, there are lesbians who would genuinely enjoy dick...except for the fact that it is attached to a man. For some it isn’t the dick that is a turn off but men in general. Penis envy is a real thing lol. So again for guys, I don’t think being curious about what a real dick would feel like or even enjoying a real dick would make him inherently attracted to men or wanting to date men. Plenty of straight people date trans people and gay people date trans people and are not bothered by whatever genitals their partners has. They don’t suddenly start identifying as bi or pan simply because their girlfriend has a penis or their boyfriend has a vagina.
So is isobe bi or does he just like it anal with girls
