For me, it's first about visual. If it were dominance, then I would think that it would turn me on to give a facial to a woman whom I either don't get along with or whom I don't care for. But I've never thought that way. If a woman and I disagree or even don't like each other, then my sexual desire for her is zero.

I think it's more about acceptance. A woman allowing a man to cum on her face shows submission, but in a loving way. If a woman says it's okay for me to cum on her face or she's hoping I cum on her face, then it says she loves me or wants to be intimate with me. The acceptance is a huge turn on.
