I love giving facials to my wife and kissing her cum covered face as we continue with sex. It's just hot having the taste and smell of cum so close to your face while doing everything else. As far as receiving facials, I prefer to swallow a guys cum but if he likes to cum on my face I let him. It's about pleasing the other person to reach my own pleasure.
Getting a facial seems like a waste of cum. It should be in the mouth where you can taste it before you swallow
Watching it in porn is cool, but I would rather it be on the ass, in the crack, in the ass, or in the mouth.
