My mind gets clouded....

So when i have sex and i climax real hard my mind gets clouded. I get high and its hard to thinknstraight. It takes time to recover. I used to chase that high doggedly. The mind numbing affects. Id become compliant and that is usually accompanied by either a burst of energy or a serious bout of lethartgy depending on how the sex was. Never could control which one i got. After i came down from my high i could coast for a while but slowly anxiety would creap in, my body would tense and twitch ( most of the time not visibly i dont think but idk since its not like i was looking in a mirror while it was happening) and I'd start craving it all over again. Dose this happen for anybody else??? Im sure these are not the onlybthkngs that happen but its also not as if I was studying myself....these are just things ive noticed over time....
