Crying after masterbating?

So I recently bought a vibrator so i can try orgasming myself because idk if I ever done it before it was hard to tell lmfao. While I was doing it, it felt nice so I stopped a bit and started to cry. I couldn’t tell if I was orgasming since I was in the shower tho. I just don’t understand why I cried. I’m so confused. Idk if it has to do with my ex or stuff that has happened in the past :/
