As a bi man this is my worst nightmare. I am so scared to tell women that I’m bi. Also this might be something you have to work through yourself in therapy. But know that bisexual people (myself included) can experience attraction differently. I’m not looking for the same thing in a man as I am a woman. Ultimately: if he didn’t want you and you weren’t pleasing him, he wouldn’t be with you. But he is with you, which means he likes you
That’s all you can do besides therapy as far as I know. Support him and let him support you. Keep in mind: him being bisexual does not automatically mean he’ll cheat, and it doesn’t automatically mean he wants threesomes. He is with you, and if he feels comfortable enough to be openly bisexual around you then that means you might be pretty safe. He likes you for who you are. A lot of people have hidden insecurities. Just make sure your insecurities don’t become complete biphobia/homophobia/abuse
