My first girlfriend really really hated it when I came on her face. So, I would wait until we were doing some tie up games and she couldn't move, then I would pull out of her pussy or mouth or ass, and shoot my load all over her face. While she was swearing and cursing me for doing it, I would either use a vibrator or my fingers on her clit, and make her cum over and over again, covered in my spunk. After doing this maybe a half dozen times she started asking me to cum on her face almost every time we did it. She grew to love having my load on her face so much that she used to want it all the time, just sitting watching a movie or playing video games. Pavlov's cum, I guess.
Very true, sixincher. And your sensitivity, in a sea of contempt and misogyny, is welcomed. That's why, as a man, you should always announce your orgasm. Women appreciate the 'heads-up' and, at least in my experience, they'll swallow (or at least attempt to).
