Lesbian

Why do I feel like I’m not attracted to most guys some days it’s there most it’s not . ??? I used to be a lot now no and I do watch a lot of lesbian porn cuz come on it’s hot 🥵 right!! And regular porn just never got me off but I was thinking I was a lesbian for along time and one guy I kissed i really felt turned on but not emotionally connected I haven’t had a bf in 5 years but my other question is can you make urself a lesbian by watching pornonly and not having real sex and also can you be a lesbian and be somewhat turned on by guys or no? Kinda confused!! Help
