Classic lesbian vs Bi dilemma

Ive been saying im a lesbian for like 2 years and I have a gf whom I love. I love having sex with women. My only thing is I feel like some men are hot but i absolutely do not want a relationship with one, even if I was single, and I don’t think I want to have sex with one. Also these thoughts came up two days ago and I am known to use a rather unstable personality so it could be that. Also I only like fictional men or actors so what does this mean for me? Idk if im just finding some guys cute like “awww a cute puppy” or when I find them hot it’s because I like muscular aesthetic more so than I like the guy himself. Thinking about it I could possibly top a guy with strap but the again like why not just do that to a woman, hello? I could not be fucked though, I barely let my girl do that.

I also feel like if I am bi or Omni or smth then im letting my family down because I could’ve fell in love with a guy and been “normal” but instead I love a woman. Dont get me wrong i love my partner and I plan to marry her, but my family isn’t too fond of that(actually they don’t know her haha)

Also biphobia is such a thing in queer spaces and I feel like I might be biphobic(not on purpose) a little, because I’m scared that I’ll be “less queer” or something. Do any of you guys feel less queer?
