I wouldn’t be able to wear this skirt if I was a boy.
My penis would be clumsily dangling down by my thighs. I would probably get put in jail for indecent exposure.
If I accidentally got a boner, it would lift my skirt up and expose everything, including my balls. That would definitely get me in jail.
But since I don’t have a penis, I don’t have to worry about that! I can wear this skirt all sexy, out in public, and no one can stop me.
