Really?!?!

So last night was amazing. My husband and I had sex several times which itself is nothing new. The last time he couldn't finish because we had done it so much in such a little time. Its happened before when we have sex multiple times so it wasn't anything new. Normally, we will just lie there and cuddle and forget all about it. However, this time I balled like a baby. And i couldn't even explain it. I wasn't upset by it or angry. I just couldn't stop the tears from coming. I felt so stupid. I never ever cry because of something like that. I usually only cry when im super pissed off or really hurt lol what the hell is wrong with me?
