Guys, when a lady's clit gets oversensitive after an orgasm, it HURTS big time if you keep stimulating it. It is not fun -- agony is more like it. If your lady says "stop" you should listen, and move on to something else for a while. I am not sure if there is a solution to the overstimulation problem, it may be that it takes the woman learning how to orgasm from less clit stimulation in the first place (more G-spot or something else). I'm experimenting with this myself. But the bottom line is that once she gets to the point where she can't take more stimulation, you need to back off her clit. If you are in the middle of sex and don't want to stop, just change your position a bit. I think ladies probably vary a lot in how long they need to recover before the clit is OK for fun again. I know that it varies a lot for me depending on activities -- sometimes I can go again right away, sometimes I am sensitive for half a hour. Just be attuned to your lady on this one, the pain is pretty intense if you overdo it.
