Post orgasm dreariness

Idk if the label fits, but I have noticed that every time I (F) orgasm I immediately feel terrible afterwards. More specifically, I feel empty and completely drained, so much so that if it happens after masturbation it takes me minutes just to remove my hand because I don't feel motivated enough to move at all. I know that it's relatively common to feel tired or even sleepy after orgasming, but that's not. For me it's literally dreariness and numbness as soon as the orgasm subsides (and they are usually very brief, about a couple seconds). Is it normal or should I be concerned?
