Dale, welcome to the boards. It makes your posts easier to read if you don't use all capitals.

In any case, is she using a vibrator or other type of clit stimulation to reach orgasm? If so, then it's actually pretty common that she can go numb due to the pounding her clit is taking from the vibrator. You might try a different type of vibe or something as easy as switching to fingers in lieu of any type of toy. The soft finger tip attachment on the eroscillator is a great choice for a non-numbing solution to a toy if she's ultra sensitive.
