1. Good and bad kiss criteria differ.
2. INFJs kissing styles differ.
3. Kissing (like everything else) is a mutual act. The responsibility is shared, because we inspire each other.
I've had the luck to have kissed some INFJs and on average I enjoy it a lot. So passionate and involving! That doesn't mean that objectively speaking it's good, some kissing experiences with INFJs were disasters, but still so full of emotions. I think I remember the disasters with even greater joy, and they are very dear to me. Imagine how boring it would be if all the kisses were always perfect. I guess it's more important the feeling that we may have by just the fact that we want to kiss each other, and then... if something goes wrong the moment instead of being ruined actually can be remembered as very sweet. Oh, I must also mention that I simply adore moments of clumsiness.
Even very experienced INFJs are sometimes completely lost, but it's so lovely.
