Hmmm... not really sure I understand your question. It sounds like you are able to achieve a very strong orgasm from clitoral stimulation, you say you shake uncontrollably, which I think is fairly normal during very powerful orgasms. What I don’t understand is your statement that you can’t seem to keep going -?? What exactly do you mean? Do you mean you have to stop stimulating yourself? I would think that’s somewhat normal as well - for many (if not MOST) females, the clitoris becomes hyper-sensitive immediately after orgasm & there’s no desire for additional stimulation at that point. I’m a guy & basically the same thing happens to my penis right after orgasm - I might enjoy add’l stimulation for a few seconds after orgasm/ejaculation, but then it becomes too sensitive & add’l stimulus at that point is uncomfortable. So if that’s what you’re talking about, I’d say that’s pretty normal. If that’s NOT what you meant, please elaborate, fill us in a bit more...
