needing advice

so i have been in a relationship for two years with a man… im really starting to question my sexuality and perhaps spiral. recently i have been thinking i could possibly be a lesbian. i’ve never even so much as kissed a girl. i think i’ve repressed it due to growing up where i did and things like that. however now that ive been thinking really hard about it for the last two weeks, ive kinda always had “crushes “ on women. nothing with my boyfriend feels the same and ive just been generally irritated when he tries to initiate intimacy. any advice for navigating these thoughts and finding myself ?
