I love it - as long as it doesn't go in my eyes. :shock:
I guess it is a measure of the influence of porn on our sex-lives that quite a few guys like to do it and quite a few girls like it too. As far as I know, cumming on the woman (rather than inside) started out because porn films wanted to show that not only the sex was real but that the man really was having an orgasm. I guess that might be one reason why female squirting films have become more common recently - after all I don't know about you but if I'm watching porn I really want to believe that everyone involved is having a good and sexy time. And what better way to prove it?
I'm not sure why facials in particular are the norm in porn but I suspect, like Lost, that it is a link to domination. It certainly feels very potent and powerful, thinking about the idea of cumming over a woman's face particularly rather than boobs or bum or wherever.
I love having my cum licked off my own body - that feels great!
