very confused?

hi so this is just gonna be a jumbled mess but ok so

basically ive identified as a lesbian for a while now; if there's a girl and a guy walking side by side past me, i'll look at the girl instead of the guy. the only porn ive ever felt aroused from was lesbian, and my first and only love was a girl. everything seems alright.
but there's a problem: lately i've been thinking of one of my guy friends who has confessed that he likes me and usually when a guy likes me id laugh it off and not even think of it, but for some reason he's different? i've never really thought about sex with a guy and actually liked the idea, it's always been girls, but now im just really confused because i wouldn't mind having sex with him. i like using phallic things during sex, so it's not like a penis grosses me out completely or anything; i just don't feel attracted to guys, if that makes any sense?

i'm aromantic, so i don't have any feelings for him or anything, if i did it'd just be more like a close friendship than anything. i'm not worried about having feelings for him, i'm worried about my sexuality now.

i've thought of identifying as homo-flexible for a while, but i don't think i could even use the term because i'm more attracted to girls than guys, like i've never been attracted to guys ever. calling myself a lesbian just feels right, and i don't want to have my sexuality invalidated because i find myself attracted to a guy for the first time. i used to identify as bisexual/pansexual but i quickly stopped identifying as that because i only thought of girls, not guys. i've dated guys for most of my life, but those were just little 6th grade relationships that didn't mean anything. with my last boyfriend, i truly realized that i was actually a lesbian and not bisexual. he didn't have feminine curves or long hair or just feminine features. he wasn't what i wanted. i wanted a girl, not a guy. so being bisexual just doesn't seem to make sense for me.

am i truly a lesbian if i feel sexual attraction to a guy? is there a label for this besides homo-flexible? this whole post is just a mess and i apologize for it, i just wanted to get people's opinions on it. thanks for reading (*hug*)
