Dating no physical contact
Let me lay out what I view to be applicable biblical principles and passages on this topic.
Robert Epstein, senior research psychologist at the American Institute for Behavioral Research and Technology in California, studied what he calls Western-society love matches, and compared them to arranged marriages.
God instituted sex within marriage as part of His design of the family (Genesis ).
In 1 Corinthians 7:3 and following, Paul says once we are married, our bodies literally belong to our spouse; he also instructs spouses to meet one another’s sexual needs and to be together regularly so as to protect ourselves from falling into ungodly lust and extramarital sexual activity.
We need to address the whole spectrum (“just kissing” included). First, the fact that “romantically oriented” is in italics above is important.

In some cultures, kisses of greeting — between members of the same sex or of the opposite sex — as well as hand-holding and other forms of physical expression during normal, non-romantic social intercourse, are more common. You might even be able to talk me into the notion that , “non-leaning-in” hugs of greeting, sympathy, etc.
