Could I be a lesbian?

So im a 22F and im in a relationship with a 21M. Im beginning to question my sexuality.

So we have been together for nearly a year, previously we had been together for 2 years but we split up for 9 months due to him being a poly addict.

Im feeling really confused about my sexuality and idk if its because im not attracted to men, or that I am no longer physically attracted to my bf. That sounds really harsh, and I do love and care about him, but whenever we hang out we are not affectionate towards each other, we rarely ever have sex and in all honesty I dont like having sex with him. Its not that hes bad at it, I am just really hesitant to have sex with him and sometimes it feels like I have sex with him to make him happy, rather than because I actually want to do it. When he comes over to mine, we rarely ever cuddle. We do kiss and hug eachother as a hello and goodbye, but thats about it. He has also kinda let himself go a bit because of his MH and addiction to substances. I feel like such a bitch typing that.

Now this is where I am questioning my sexuality. I have always found women really attractive, more so than men. For example, if I see a fit woman when im out and about with my bf, im always the one pointing it out to my bf and we have a running joke that I would be a lesbian if it wasnt for him. I have had sexual relations with a woman before when I was at uni. Ive never had a crush on a man, ive only ever had crushes on women. The first relationship that I was in was with a girl, it was only for a day because we were only kids. Being in a relationship with a man has always made me feel quite anxious and a feeling of it not being right if that makes sense? Also, when I watch p*rn, its alwaus lesbian porn.

When i was in college, I identified as pansexual, rn I would probably say that im bisexual, but maybe im fully lesbian? Men do kinda scare me but thats because ive experienced a lot of trauma when it comes to men and SA so that may be why I feel this way towards them. I dont feel scared when it comes to my bf, and he has been my rock through hard times, and he always supports me.

I just dont know what to do rn because I dont want to hurt my bf by breaking up with him. Hes struggling a lot with his MH atm and he needs me in his life. I do care for him, and I do love him, Im just unsure about our relationship atm. Sometimes I kinda wish that we were just friends instead of partners so that I could support him and care for him as a friend, rather than a gf.

Could this just be a bad spot in our relationship? Could I be a lesbian? Has anyone else been in a similar situation as me? Please give me some advice because I genuinely dont know what to do moving forward.
