I’m bi and nobody knows!

Hey everyone, I’m 18 years old and over a year ago I bought my first dildo. Because I was curious I told myself. But pretty soon after I used it again and again I realized it was more than just curiosity. But still I got sick of the idea of a men’s face, I only loved dick. Now more than a year later I found out I love masculine dominant men, even their faces turned pretty and I even want to have a heavy makeout that would make me throw up a year ago. But now I know I am bi, I love men and women and I have nearly two whole bed stands that are full of dildos and girly clothes (because I’m more of a Sissy and I love being more girly) and I once realized one of my underwear’s that was in there was gone and was back later. What meant my mom washed it and found my whole collection🤭 but I didn’t told anyone yet. And still I have never told anybody even not my mom that definetly knows it. My question is: Do I tell her and explain I am just orienting my sexuality and I’m bi right now, or should I just wait till she tells my dad (if he doesn’t know it yet) and they will ask me about it? Thankyou😘
