Well, if it’s just about sex, I suggest “No more than twice with the same guy/girl” rule. I came to realise that if you sleep with someone three or more times feelings happen. I wouldn’t classify it as love, but it’s true that a certain intimacy and possessiveness develop.

But it seems to me (and I could be way off the mark here) that through sex you are trying to find something else. And until you identify what that is you will continue to “overreact”.

One other thought, I have heard of women who react to orgasm so strongly that they are reduced to crying wrecks every time. Perhaps your reaction is something similar.
