Thank you for your replies.
I have a kind of embarrassing and exciting post to make.
My fiancé took me panty shopping today. OMG! How uncomfortable! I would have died without her.
There I was, my fiancé looking through racks for me (I was afraid to be seen getting my man germs on somebody else's potential skivvies), watching as she looked. I was completely afraid to offer my opinion. Eventually, when nobody else was around, I suggested something simple and utilitarian (Ha! Just like a guy!). Much of what I saw was just too girly. It would remind me of what I am, not who I wanted to be. Finally, she showed me a pair, just as a ciswoman started to browse the same isle (eek!). I said, "OK, let's go!" (just like a typical man).
We got in line, and finally, to the register. My gal handled the transaction. After the panties were purchased, I wanted to carry the bag, but then I thought that may be deemed weird. So, I waited for my fiancé to take the bag, and we walked out together.
I certainly was not acting like myself in the store.
But hey, I went panty shopping today! I survived!
It was a huge step... even though I did not feel free to act like myself (mental hang ups). Ciswomen would not have the difficulties I had today.
