Coming out 17F

New here!! Ok to start, I’ve been out as bi for 4 years, and attracted to women since I was 5. I am in between if I’m lesbian or not. I only find ONE male celebrity cute, so I’m not sure what that would be considered. Anyone have any obscure ideas of how to come out to my mom?? I saw this one TikTok of a guy who gave his mom donuts and was like “here’s donuts…I’m gay”. Basically something stupid.
