No,I am always replete after masturbating, unless I was cheated out of a satisfying orgasm. Sometimes,when trying to build up, then back away several times, I get too close to the edge and accidentally go over before I am prepared. That's when I have a less than satisfying orgasm & I feel like I'm missing something. But that's only because once I have orgasmed, I have a refractory period (just like a man) and if I don't have my usual strong orgasm, I have lost my chance for a while!

Sometimes I feel like something is missing, but that's only when I don't really feel satisfied from my orgasm. Thankfully though that only happens once in a blue moon.
