Confused

Hey i’m a 22 (F) and I have been labeling myself as bi/pan since i’m about 14/15. I currently have a boyfriend. We’ve been on and off through the years but now we’re back together. Recently I feel like my thoughts are killing me, that I haven’t experienced enough with woman (I’ve dabbled in hookups but not a relationship). I also kind of get this weird feeling lately when I have sex with my boyfriend. It’s not disgust but I feel like I’m not 100% into it. I’m sure I sound dumb but I don’t know where this sudden feeling of a need to be in a relationship with a woman came from. Yes, I have expressed this to my boyfriend plenty of times and he fully supports me being bisexual but of course he loves me and is upset by this as well. Honorable note, I have had sex with a few other men as well and only felt I needed to do it to validate myself. I’m not sure what I should even label myself as at this point but I obviously know the clean cut truth is to breakup with my boyfriend.
