I agree with ATC & Pequod...no worries. Just a release, there's nothing wrong with you. Women have periods and sometimes cry after sex, particularly when there's the need for release, and I don't think it's necessary to try to figure out where ir comes from because it could be many things. It could be sorrow coming from places far beyond anything you could understand would be affecting you...or built up frustration from something unrelated. Women are different creatures from men on many levels...mental, emotional, spiritual...just be with it. It's all good, as long as no one's freaking out about it.
