Hmmm... since I have gone down on a chick, I feel it would be hypocritical of me to say that I wouldn't go down on myself.
Plus, I have tasted myself on my husbands lips and dick before during various sex acts. So I guess I'd have to say that if I could I would.
But I can't.
So there.
PS- I would think about every woman who has been given the lickey-lickey treatment has kissed her SO after, thereby tasting themselves. What else about licking yourself would be gross?
