Except for one girlfriend who was an absolute freak of a cum junkie, I've not stood there like they do in porn and jack off until intentionally firing away point blank at a woman's face. Nevertheless, I've pulled out of mish many, many, many times and let fly where it may resulting in hundreds of vag-to-forehead spraydowns. A fair few times, I have slid out of a reverse cowgirl and cranked some rather impressive shots onto or over the head of my paramour.
And by way of equalization, I've hit myself in the face a whole boatload of times over the years (mostly from jerking off but a few times from those reverse cowgirl shots that flew way, way up and over her head, ultimately landing on mine). Not on purpose, really. The first few times to see if I could and to gauge the experience. Many other times because I just couldn't be bothered to intentionally aim away.
