Hey, thank you so much for reaching out. I'm sorry to hear about what you're going through with your friends, that's a really tough situation. I'm also bisexual and I'm quite familiar with the feeling of entering certain interactions with the fear of not being accepted, or being in interactions where people say things that are either blatantly or subtly homophobic. It can be very uncomfortable.
I think there may be some benefit in setting boundaries and bringing it up with your friends directly, as ABC01 has suggested. The ability to take accountability for their words and behaviour may reveal a lot more about their character than the comments that they make. If you do bring up in a gentle way how much what they say is affecting you, their response will tell you a lot about the intent behind what they're saying, and also their propensity for being accepting and kind.
Do you have any other loved ones or family members who you're out to, or who you'd feel comfortable opening up to about your sexuality? It may help to have other people to either discuss your feelings with. Particularly if you have other friends who are in the LGBTQIA+ community, sharing similar perspectives and experiences can help you feel comfortable, supported, and safe.
I hope this helps, please feel free to chat some more if you'd like. Being queer myself, I know a lot about LGBTQIA+ experiences from both my own and those of friends, and I'm happy to offer any more advice or reassurance if you need.
Take care, SB
