TMI question… ladies who are into rough sex lol

Sooo my husband and I have been married for almost 7 years, and we tend to be pretty adventurous in bed. With the addition of a new baby (who is almost a year old now) we had gotten into the habit of just having quickies wherever and whenever we could (we usually have sex 7-10 times a week sometimes more, don’t judge 😂).

Anyways, since it has been awhile I wasn’t totally expecting it when he said he “had plans for later” and then had laid out a whole kink session for us (notably he is the dominant one here). Anyways, that part was euphoric. But something that puzzles me to no end and it still happened back when we had more alone time and were super kinky regularly… is that I CRY at the end. Every time. And it always makes him so worried and he spends a loooon time hugging me and kissing me and trying to make sure I’m okay because he is concerned over the fact that I manage to burst in tears afterwards every time. He’s always asking if he went too far and etc (we have a safe word and I would use it if I needed to and I know he would stop if I did). Anyways. IT MAKES ME FEEL SO BAD. Because I’m FINE. I’m not upset at all. I feel happy and relaxed and definitely feel safe. There are no negative emotions. I don’t understand why I cry. Does this happen to anyone else? Is it just an emotional response to the physical intensity of everything? That’s the only thing I can come up with but I was curious if this happens to anyone else??
