please help?

i already posted this on my other account but i feel like this one gets more traffic so i'm pasting it here too

okay so i'm in spanish three and for part of our final we have to give a 3 min verbal presentation. luckily it's about anything we want, but there's a little problem. i want to talk about gender neutral pronouns (like elle/la, ól/ol) but if i do that i'm almost certainly going to out myself. that's not a terrible thing bc my school is really accepting however my spanish teacher is a family friend and she would almost positively use gender neutral pronouns for me around my mom. my mom is generally accepting of the lgbt community but she's said some mildly transphobic things to me in the past and she keeps on telling me that if i "were trans, i would be sad that you changed ur name" and misgendering a couple of my friends. do i take the risk and come out to her or should i spare myself and do it on something else.......
