did anyone go from lesbian to bisexual?

I don’t know where to post it but please don’t take it the wrong way I know I’m a coward but I really need advices (also english isn’t my first language so sorry if I make mistakes)

for context I’m a lesbian, I always knew it deep down but I fully acknowledged recently and I don’t think I’ll ever be able to accept it no matter how much time pass

since I recently heard that sexuality is known to be complexe and fluid I want to know if I could end up feeling attraction towards men later in life? I’m still young I’m 20 so I think I need a few more years to be fixed on my sexuality and might eventually come to like a guy at some point since it’s fluid and you love someone based on their heart not what they have in their pants, I don’t think that being a lesbian is wrong btw, I really love seing happy lesbians on social media, you deserve it, but I just don’t want to be a lesbian myself you know, I just want to have a normal life without giving up on my family, friends or god

so even if I totally get that bi women themselves struggle with their sexuality I think that me still being somehow attracted to men would maybe help me not want to just give up on everything, I had such very nice guys who were into me in my life but because of my lack of attraction I unfortunately couldn’t return their feelings even tho I tried, I just want to hope that maybe I’ll be able to want to marry a cool guy without feeling like shit tbh, so I want to know if there might be a few women on here who maybe developed bisexuality as they grew up or if you think it’s fully over for me?
