I have to tell someone

I’m bisexual. I’ve known it for years but always floated between I’m not lesbian and I (F22) still like some men. My current boyfriend (27M) is always suspicious of my interests in women and jokes about it because it clearly makes him uncomfortable that I would be interested in both women and men. I’ve never been in a relationship with a woman and now that I’ve been with my boyfriend a few years I’m starting to regret that I’ll never get the chance. I’ve made out plus gone a little further with many other women before I met him and was exploring myself in college. He’s adamant about not even exploring options with other partners or experiences and even sees porn as cheating. Any time I try to bring up my feelings he shuts me down completely and interrogates me with the are you sure you’re not gay schtick. We’ve been off and on for three years, but I really feel led to explore my feelings with women yet he really limits me on what I can do. Not sure what I’m looking for here, I never make posts like this but I need to get this off my chest.
