If a reg (under his assumption you get along, have had good talks during extended visits and time was good) told you he had begun to catch feelings for you, and thought it best to not see you or have contact, how would you reply?
So true. Some the inner labia, some right on the clit with light pressure, some with moderate pressure, some a gentle suck on the clit, some on the runway leading up to the clit, some on top of the covered clit, even one on the posterior commisure (the bottom of the vaginally opening), some need a digit, etc etc. To me, a chunk of the fun is trying to figure out how a woman is wired...but good rule of thumb is always to start gentle until you figure out her comfort zone.
