I agree with your point about the oversexed atmosphere.
The sensible definition of "homosexual" is an activity (or, in christian life, at a stretch an obsession with it) and needn't be considered an identity of a person. (I am not querying individuals' current definition of "identity".)
Last time I looked, about sex the law said - consenting - adults - private.
Numerous side issues don't have to be packaged into the deal.
Individuals can embrace their private definitions and even shared definitions of course.
God doesn't see "orientation" except as there is something concrete going on to orient. He keeps it simple!
1. Here we have a thing that's more complex and most individuals will be amidst an evolving scenario. A relationship that is in the process of becoming chaste
may still be
thought by either party to be "romantic", whatever meaning they attach to that (I've had some friends like this so I saw or they told me).
We needn't necessarily attach our values to other people's names for the concepts. It's good to equip others casually and not pointedly, to stand up for their individual wants as quickly or slowly as they want. We can leave people space for their own minding of their business.
2. For some, they may find their "partner" in the sense of spouse (or similar), and they may still think of other old friends in what they term a "romantic" way.
The important thing is that we model ourselves being ourselves, and only stand up for those not able to enforce their own boundaries. This does NOT involve fussing about "orientations".
(Am not sure what view Molinist-Preterists have about how God sees things?
