My experience is negative: one girl I asked and did a few times, facials, she didn't like to either like or dislike it, I think she accepted to please me, she liked it on breasts and belly; another one didn't want me to come elsewhere than inside her, once I did on her back she said she liked it; another one with whom I can openly talk about this stuff said no way in mouth (she said she tried and didn't like) and no facial...
Being a man I like the idea, I think it mostly comes from our addiction to porn but even when I was allowed to facial or to in mouth at the very last moment I changed the target...
I wish one day to find one who likes it, would like to experience how it feels by knowing she doesn't do it just to please me but to please herself (if they exist).
