10. Say that you’ve had better
It’s absolutely normal to not like all the partners you’ve been involved with. It’s also understandable that not all of them have made the same impression on you. Some of them might’ve been so impactful, that you can’t forget about them.
However, whether you’re in a long-lasting relationship with your spouse or you’ve just started dating someone, it’s absolutely impolite and overall WRONG to compare their performance with someone else’s.
Even though you might be mad or frustrated when you say it and you don’t actually mean it, you actually give off the impression that you don’t care about that person’s feelings and the whole connection between you two won’t be very strong either.
