You're using paint on skin - paint in fact that's known for it having to be strong enough when applied to deal with the rigors of an office day without chipping (too much).
Like any product that wasn't developed to be applied for skin and particularly not developed for skin so delicate as the genital skin - it can, potentially, have some harmful effects.
For safety's sake i would urge you to switch to something along the lines of an eyeliner pencil, or - for something a little more permanent - a marker without additives to the ink.
