I cried after sex?

So, I cried after sex the other day uncontrollably and for no reason.. Can someone please tell me wtf that was about?

Nothing bad happened. I wasn't on my period, I'm not pregnant. It was normal.

We had great sex, and the second I laid down... I just blubbered like a baby and I have no idea why. Haha.

It just threw so much emotion at me I guess.

Anyone else ever do that???
