9. Say the wrong name
…Do we even have to discuss this one?
Saying someone’s name during that fun and exciting part might make both of you more engaged and enthusiastic, which might result in a very well-deserved ending (if you know what we mean).
However, things can completely go the opposite way and turn into a disaster if you make a mistake and say the wrong name. And that’s not all. You might give off the impression that there is someone else in your head, someone you wish was there with you, instead of your significant other.
…This can easily break off your relationship, so you better not say the name wrong!
