what are your personal pieces of advice to minimize gender dysphoria without outing yourself?

I paint my nails dark colors. It was scary at first, but I only ever get compliments on them. Black is a pretty acceptable color for guys these days.

Shave your legs/body hair. Shaved legs is one of the best feelings in the world and even though it doesn't feel like it, literally no one notices.

Use feminine hygiene products. If you don't already, you won't believe how much better the scents are. I wish I had let myself try feminine deodorant/body wash years ago. Also, no one will ever notice that either.
