2. Your intimate history
Besides talking about health matters that might be caused by intimate adventures, talking about what your romantic life used to look like with other people is a no-no because it’s one of the things your partner should never find out.
You can let your SO know about the people you’ve been with along the way, but you don’t need to give too many details about what you did, how you did it, what that person liked, etc. It simply doesn’t have a purpose, and it won’t benefit your relationship at all.
Have fun and keep things spicy now in the relationship you’re in, but don’t tell your partner what your former lover did, expecting them to do the same thing. It doesn’t work this way, and it can lead to a fight and even a breakup!
