as a combination of several of the posts above, i cum (is orgasm a verb?) repeatedly for hours in waves that might last up to a minute w/ these series happening up to a dozen times/hr. the orgasm series is more or less intense depending on what was just done, but anything works. i’m sensitive all over all the time, can cum by being kissed (most anywhere), have afteshocks even when lying quietly & untouched, & have episodes of being awakened from a sound sleep by a wave of orgasms.
it’s lotsa fun but anything over 5 hrs or so & i’m really worn out.
that being said, your g.f.'s sensitivity to the point of not wanting to be touched is also normal. but as suggested, ask her if she is willing to experiment. she might find the intensity better than she imagined. if instead, she finds it just annoying, you don’t do it any more.
Please mark me down in the multi-orgasmic column. I seem to be a lot like Popsyn. Lots and lots and lots of orgasms, and then at some point, my nervous system gets overloaded and says no more. At that point, being stimulated is unpleasant - not quite painful but definitely uncomfortable. So, if you’re sweetie is like that, definitely back off and go for the cuddling.
Post-orgasmic sensitivity can be overcome with a little practice and I highly recommend it for both parties. When we were younger, the sensitivity was so strong that neither one of us could stand prolonged post-orgasmic contact… however we used to tease each other by making each other endure it as long as we could stand it. After a while we realized that we could take more and more, and aft-play (as we began to call it) became an essential part of sex. We’ve found that we can have more orgasms and the second and third orgasms can be stronger than the first. Also, there’s no flacid period for me between orgasms, so I’m more useful… if you know what I mean.
