I've never ejaculated on someone's face.

At least not purposefully. is this aberrance.

Is there any other way to ejaculate?

I only did once or twice, intentionally. Surprisingly, it did very little for me in terms of heightened arousal. Which makes me think that my fascination with that particular custom has much more to do with witnessing the degradation of the female, than with the sort of vicarious arousal I experience upon watching scenes of penetration.
