How exactly do you think bisexual or pansexual people function? Do you think they just don't have friends? If not, why is it different for heterosexual people? I genuinely don't understand. I'm not trying to do a 'gotcha' or a win a silly internet argument or anything like that. I just genuinely have never understood it and I want to so I keep trying. My best guess so far is it's just a mix of insecurities and weird gender norms and heteronormativity.
