Paralyzed??? ORGASM???

So me and my boyfriend were having sex last night in the back of the car.. 😏 Hot Sex... Our position was missionary. I was really enjoying it and it felt so nice. So my finger tips starting going numb.. I was really scared. Then my whole upper half my arms and fingers and my FACE. I FELT SO SCARED. But i was still enjoying it. I didn’t know what to do i didn’t know what was happening to me. I went home and looked it up later that night. Says i was having an orgasm or was right about to?

Any input on what it could be? did i actually have an orgasm? was my body numb cause blood wasn’t flowin likeee girlssss help ME. 🤯🤯🤯🤯
