Remember how jealous you were the first time you found out boys have balls but girls don’t? Didn’t it feel unfair that you were burdened with a weakness the other sex didn’t have?
Let that jealously motivate you.
Once you feel how good it feels to wear panties as a girl, how snug they fit, you’ll know you made the right choice.
Seriously, why would anyone want to be male if given the choice?
If you need motivation, just hit yourself in the balls really hard. As the pain throbs deep within you, understand that you wouldn’t have this weakness if you were a woman.
