Wtf happened? Is something wrong with me?

So, I'm a cis man. 50. Divorced. 3 adult children. Everyone of my friends thinks of me as a badass. Tattoos, piercings, long hair, attitude. Listen to metal. But, I've always liked panties. So, I bought a couple pairs from Walmart that I thought were super cute, and fit great. Then my brain, which is apparently thinking like ai, spouts off with, you need a matching bra. I don't have boobs. Brain says, get some. Then feelings come out, and it snowballs from there. I want my nails and makeup done. I want to shave all my hair except arms and head. I want to be sexy and pretty, and badass now. I want to be a woman. These feelings all snowballed, and I'm a little freaked out, and want to cry, but it doesn't feel wrong. Advice? What's happening to me?
