Help!! My boyfriend has become more and more feminine and when I met him he was really masculine and I was very attracted to it

And don’t get me wrong i have nothing against the lgbtq+ people but I just don’t see myself being with a girl. He mentions everyday how he feels like a girl and he gets really offended anytime I ever mention I don’t like his feminine side

But I’m so in love with him , I lost my virginity to him and we’ve been through everything together. What do I do?

Note: he’s also bisexual and I’ve asked before if he’s just gay and he cried and it really offends him anytime I ask that
