Confused and questioning🥲

I, 25 (she/her) and my fiancé 28 (he/him), have been together for about 5 years, engaged just shy of a year…. Well I have always been open about my sexuality and being bi and having romantic encounters with women. I’ve only ever dated a man though as for the way I was raised in a religious household blah blah you know how it goes… I explored on my own but never openly and freely. Anyway… we’ve been together and I’ve struggled with thoughts of could I be a lesbian? And thinking of being with women and struggling with wanting to have sex (clouded though by a history of SA by men, making things with that complicated in general) this past weekend I finally opened up to him about a lot of it and we talked a lot. But now I’m still confused and left with a lot of question and still confused. We even talked about letting me explore and he said if it hurts him it would be his job to let me know and to be open and honest about the communication. I’m afraid to hurt him still though and. What if we do that. Open it up or he lets me be with girls and then I end up finding out I’m more than just bi? Like if I feel like a feeling Id never felt or something that changes everything. And does it mean my love for him isn’t strong enough because I’m having these thoughts and question? I think I just need advice or something.. anything. Guidance. Idk lol. Pls help idek if this is the correct subreddit for this 🏃🏼‍♀️‍➡️🏃🏼‍♀️‍➡️🏃🏼‍♀️‍➡️
