I don't need kissing with tongue. I dont like spit. I dont necessarily need kissing at all. Sometimes it feels forced and, well, nothing forced is good or is meaningful. Period. So if you dont like kissing, dont push it. People can tell.
Why NTs view it as a "lack of love" is because for centuries, for as long as romantic love has existed, kissing has been an expression of affection, attraction, and sexuality. They say the lips have the most nerve endings in them- although I dont know if I believe that.
For me, kissing on the cheek or lips (no tongue) may come naturally. You know, sometimes, if you're in "The Act," you may naturally want to kiss the person, because it feels like you are feeling them in more ways than just with your body.
If an NT who is in a relationship with you wants to plant one on you, know that it isnt' about sensory stimulation for them; instead they may feel overwhelmed with affection and that is how they show it.
I'm not offended if my boyfriend does not want to kiss, I actually prefer not to. But sometimes I get that urge to.
