oh, oh, oh! Flash of inspiration...
So, how about you give her oral sex to orgasm, wait a few minutes (maybe she can reciprocate) for the sensitivity to subside, then have sex! Or does the sensitivity last for a long time?
If I get off really quick I can usually get back to intercourse in just a little while. About the time it takes to change positions.
