Orgasm so intense you start crying

Has this ever happened to you? If so please explain.

I’ve experienced this twice with my boyfriend. And this last time was so beyond intense. I felt so out of control and out of this world lol and that’s the best description I can give. I literally just had to lay for about 30 min to gather myself and contain myself enough to stop crying lol. I don’t think it means anything bad to cry while having an orgasm, I just would like to know how or what causes it to be so intense lol.
