What mistakes do we make during a kiss:

1. Lots of language. The tongue should be a condiment, not a slippery jellyfish main course. 2. Wide open eyes. There is an opinion that we close our eyes if we have feelings for a partner. So you better close your eyes. 3. Passive aggression. It is not necessary to be timid much, but also active. Passivity will be perceived as unwillingness and uncertainty, and strong activity can scare.
