Has anybody else had intense anxiety after an orgasm?

(Female btw) For the first time out of 8 years of masturbating, I had anxiety after a very intense (clitoral) orgasm. Now, I can't stop going to the toilet with how anxious I am. Anxious for absolutely no reason. I don't know if it has to do with all the dopamine that was used up during orgasm and how I'm totally depleted or what. Just popped my Xanax. But, yeah. Strange… Any body else?
