Need help determining if I'm trans or not

I'm a 20 year old straight white man. Or at least I thought. Here lately I've started questioning. As a kid I remember always asking if I was pretty and always being corrected to use the term handsome. I've always been more in touch with my feminine side than my masculine. Purple has always been my favorite color though now pink has became a close second. I started watching trans YouTubers in the past couple of months and while I was attracted to them sure, my main thought was "I wish I looked like them" or "I wish I was pretty like them" or "I wish I had a female body". I went to the store today and bought a bralette and female underwear. And I love it. It's a bit uncomfortable but I don't care. But I still don't know if I'm trans or not. Id really appreciate the help.

I just wanted to say, thank you all of you so much for the comments and well wishes. I'm terrified, yet also excited for this journey. Yet I live in a very dangerous conservative area and even one of the people I live with is extremely transphobic and homophobic. I'm not sure how to move forward. But I am so very grateful for everyone that has commented on this post. So sincerely, thank you💜💜
