Okay, this is more like it.
The term “romantic friendship” describes a kind of life-long love of philia and agape between two people (regardless of sex, but it was most commonly between two men or two women), and the expression has changed over time. The specific activities of specific couples are not interesting to me - but kissing was definitely part of many of them. However, the emotional bond, together with the existence of “activities” not generally extended to acquaintances or what we today call “friends”, was more or less constant.
You will still sometimes see two male close friends showing public display of affection that would make an American shiver in some Catholic countries and areas. You will even still see friends being bonded for life in what could only be described as romance.
However, your assumption that “priests and bishops would still be holding hands” if my claim was true, is false. Cultural influences, good as well as bad, influence Catholic societies. Puritanism, together with Jansenism, did a great job at eradicating many good things from many good cultures. Now the Church did condemn Jansenism (and Puritanism was Protestant anyways), but that doesn’t mean they lost their grasp. Since these things disappeared in the wake of those heresies, not because of action taken by the Church, I can only conclude that its disappearance was not willed by the Church.
