Coming Out to a New Partner

I recently started seeing someone casually, and things have been going well so far. She's warm, friendly, and always seems genuinely interested in me as a person. But I've held back on sharing something important, I'm trans, transitioning now, and this hasn't come up yet because we've only just started dating. Tonight, when we were cuddling on the couch watching a movie, she leaned over to kiss my neck, and it felt incredibly intimate. That's when I realized I needed to be honest with her about everything, my past surgeries, where I am now in my transition journey, even future plans that I have. I’m worried this will change how she sees me or makes her uncomfortable. But hiding parts of myself isn't who I want to be anymore. What do you think? Should I just tell her and hope for the best?
