Triggered Crying After Awesome Sex?

Out of sheer curiosity, has anyone ever just randomly burst into tears after having an orgasm? 
A few month ago, my husband I had gotten intimate, and right after, my face involuntarily just started crying for no reasons? I wasn't sad, and I have never had that happen, lol. 
My husband was a little mortified, thinking he hurt me or something, and I had to tell him through tears that I had no idea why I was crying, haha. 
I'm just curious if anyone else has had this happen before? Or know what would cause it?
