Fun fact: back in Roman times, it was manly to fuck a twink. Being fucked by another man made you a woman (in their eyes, women were inferior in every aspect). I suppose something similar happened in Greece for a good while

If everyone just embraced being queer, everything would be ok. Sex and relationships can barely survive identity politics, old school or new.

FAKE: anon thinks girls are real GAY: anon wants to fuck a twink

I think the difference is the perceived energy barrier if one wanted to fool around on their partner if they a bi vs het.

A bi guy could, hypothetically, find a guy on grindr pretty much on a whim if he wanted to. This is a much lower barrier than straight guys face unless they seek a sex worker. If you are a woman in the early stages of dating someone, where you don't know yet how much you can trust a guy, if a guy tells you he is bi that can come off as a higher cheating risk than a straight guy.

Straight guys dating a bi-girl don't have a similar perceived risk increase. Early in the relationship, guys may not even see the potential of a bi-girl hooking up with a girl as 'cheating', vs a bonus for his enjoyment. But also - finding a new girl to date is considered harder than finding an interested guy. So the 'cheating' risk doesn't feel that much higher for guys dating a bi-girl compared to a straight girl; he may feel like he is still mostly competing against other guys.

Is this fair or even realistic? No, this is based on perceived stereotypes rather than the behaviors and character of individuals.

But this plays out at a stage of dating where people don't know each other well yet and are relying on heuristics.
