Favorite Underwear: 4.5” Tomboy Shorts

TomboyX has truly had a huge positive impact on my life. TomboyX taught me to be comfortable and happy in my own skin. I have been struggling with who I am for a while now as I have only "been out" for a couple months.

I got my first pair of Tomboyx undies just last weekend from Miami pride and I fell in love. I feel like myself in these "feeling frisky" undies :) I walk around confident and proud to be gay. Thank you for being a stand in this world for young woman and many others!

You are LOVED,
