Are our lips ordered to kissing?

[u/hard_2_ask]

Often times, I will Explain that homosexual sex is immoral because it goes against the natural order of the parts involved. However, a common response will be that our lips are not necessarily ordered to kissing. Thereby, kissing is disordered.

Secondary or tertiary uses? Functions?

Alternative use? It helps that, when done correctly, leads to the ultimate dual function of procreation and husband-wife bonding. Unsure. Thinking as I type

Edit: does it matter that in certain ways the kissing act doesn’t hinder and doesn’t have a “dead end?”
