Women, what does dry humping accomplish? : AskWomen - reddit

Great part of foreplay! Dry humping is the first way I ever came with another person. I'm a grinder, not a twiddler, and rhythmic pressure on the mons is much more likely to make me come than direct contact on the clitoris. This is because the clit shaft extends back into the body quite a ways, of course.

What Are the Advantages of Wet Grinding vs. Dry Grinding?

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
