there's stuff you can read into it but in terms of actual text, you get like

Aragorn and Arwen standing next to each other, speaking but not making eye contact under the moonlight

or Sam kissing Frodo's hands a lot

but on the other hand

consider these passages

there is one deeply sensual and erotic relationship in the Lord of the Rings

and it's Frodo and the One Ring

he wants to fuck that ring so bad

I am led to believe this is the common experience with bearing the One Ring and is why Gollum is such a little nastylad

The One Ring is the middle earth bike

everyone wants to fuck the ring yeah
