Orgasm or no?

My boyfriend was going down on me and all the sudden it was painful but it also felt really good. Then it only felt good but right after that everything was too sensitive for him to touch so I asked him to stop. I didn’t notice anything major until I tried sitting up and realized I felt as if I were floating. I tried to stand up but my legs felt like jello. I’ve never felt anything like this before. Was this an orgasm or not?
