This right here. My wife never had received a facial when we got together and I had cum on every girl's face I'd ever been with, so we talked about our fantasies and what we liked and didn't and I told her I wanted to do it. I will say the first time she was not very enthusiastic about it but now especially if it's on camera she at least pretends to like it.

If its a one time thing or you don't care about the girl's reaction I'll agree with some other posters, just do it. I've probably gotten a 50/50 reaction in years past, they either love it or hate it.
