What should you not do while kissing?

Don't have bad breath. That's a must for sure. Brush teeth and keep mint. Also try practicing how to kiss. You may be bad or good you never know. What will they think If your bad. That will be humiliatingly so try focusing on that. That's also a must too. Don't be so forceful cause then it will be too overwhelming. Mind you hands, What I mean by that is don't just stand their still it will look bad and feel awkward. Touch them in their waist, face or hair. Instead of keeping your eyes open while kissing everyone does closed so try that. Ignoring cues. You partner may feel hesitant or may feel kinda ugh, eh about something so check on that too. Good luck!
