I agree, but if you are getting steady repetition in the wrong spot or even a millimeter off to the left, it's just feels like incessant rubbing. Perhaps he's jumping on the genitalia too fast. Half of it is in the head. Just the thought of you going near a part of me makes me excited sometimes. Once you get that right spot, the repetition does get one off pretty fast IMHO. You know the spot when she says "uh, right there" or just starts moving her hips a bit more.
Ok, now I'm horny.
