That's too bad. Maybe it was indeed the quantity, though I've also met women who liked it in the past but then changed. A very large lady I met upstate used to let me do this when we met, but more recently on the phone I expressed my love of doing this and she almost broke down, saying it was so one-sided and the opposite of what she needed. Which is quite understandable, though in the beginning she very clearly expressed her love of a servant role in a relationship with a man, satisfying his needs on demand and only occasionally getting something for herself. She expressed this as a very realistic and acceptable pattern for her, which our RL encounters aptly confirmed; but expectations change, and I hope she finds what she needs.
For a couple years I dated a vietnamese-american woman who detested facials or cum in her mouth, yet willingly sucked me and then sat still as I jerked off on her face or between her tiny puckered lips, even with her tongue still wagging at me if I asked for it, until the moment I started spurting, which caused her to grimace, clench, and sometimes turn away. But she kept inviting me over to her house for more of this, and letting me do it over and over again knowing exactly what I intended. I think she came from a culture where women were fairly submissive, and when I asked her several times if I should not do this she said that I should do what I wanted to her sexually even if at the time she said or acted like she didn't want it. So I did; although she had clear limits (no anal, no cunnilingus) which I definitely respected as well.
There are of course a number of online videos with women getting upset after a facial, including some who seemed ok with it until it happened. My favorite is one at heavy-r called "teen girl cries from facial"; subtitled, but the expression and verbal tone along with the words give a very clear picture of her reaction.
