Was Plato against love? As I recall, in “Plato’s Republic”, he values platonic relationships - typically same sex platonic relationships, IIRC - with no appreciation for love. Did Plato explain his position on this? Was he gay, perhaps?

Well, he defined love in various ways, which you might not have to do, but you should at least define what you mean by “love” in a singular sense before we can answer your question of whether or not Plato believed in love as you believe in it.
OK, I am open-minded enough to accept love between two consenting adults…as in a thriving, caring relationship with two partners that give-and-take equally. My last remark was not necessary.
But, I think Plato saw no value in any of the above. IIRC, he really emphasized a society which valued physical performance above all. He defined “gold”, “silver”, and “bronze” people - from which the Olympics took the concept with their awards, as I understand it. - Jinx
I think your initial assumptions on this one are way off. The wikipedia article on it might help. The term originally referred to the passionate love (philos) between two men, which excluded lust (eros), as discussed in the work by Plato called the Symposium, which had Socrates, not Plato, as the narrator.
Also, I have no idea where you’re getting the ‘physical above all’ assertion. Plato was all about the invisible world of forms, shadows in the cave etc. Plus, the ancient olympics began centuries before Plato was born and didn’t award gold, silver and bronze medals.
