Porn Grind 

The arduous task of looking for decent porno to whack it to because you have already seen everything decent on the porn sites you regularly visit. Those most likely to have to do the porn grind are those who are picky about what they orgasm to.

It took me 45 mins. to find something decent to whack off to because my porn sites don't update fast enough. Still, the porn grind is worth it.
