how do I decenter men from my life?

So I just came the realization that I'm a lesbian after I recently have been a bisexual women leaning type of girl. And as I'm coming to the realization I notice that I kinda still center men in my life. A good example of this is I'll see a guy and immediately think "I need to look good, he might think I'm cute" but I don't really care about men and I don't care about what they think about me even though i have these thoughts. I feel kinda dumb even though ik it's not. My whole life has been centered around men and I wanna know what I can do to help not center them anymore. If it helps I'm 17 so I can't go out and do a lot of things that may help this 😭. Thank you for reading!
