What does "There was so much I could not get enough of, so much I would never be able to grasp or possess, no matter how much I tried." mean here?

I would like to know what "There was so much I could not get enough of, so much I would never be able to grasp or possess, no matter how much I tried." means in the following sentences:

You smelled of water and pines. There was softness, and there was
hardness. I could sense your tan under my fingertips, and with your
strong, solid hands you drew me afresh, creating me, the small of my
back, my inner thighs … and you. Your back, your chest, your stomach,
your thighs, your cock. Hard and impossibly close beneath the softness
of your briefs, caressing my palm, obvious, world-shattering,
demanding. We moved fervently, struggling. There was so much I could
not get enough of, so much I would never be able to grasp or possess,
no matter how much I tried. And I tried, we tried. Covering ourselves
with each other, merging into one, pulling, following the pull,
letting its current take over. Our sighs were shared, refused to release us. The night reminded me of the Easter bonfires I would watch
as a child in the park nearby, where the pyramid of wood burned from
top to bottom, chasing the ghosts of winter, bringing a thaw,
releasing the warmth from the dormant, the resting. The flames would
hypnotise me. I’d merge with them, with their dancing, destroying, and
bearing. We played this struggle, breathless and elated, heads light
and filled and spinning, until exhaustion, until we released ourselves
on to each other and fell asleep entangled like weeds.

• Tomasz Jedrowski, Swimming in the Dark, Chapter 3

In this novel which is set in the 1980’s in Poland under the socialist regime, where homosexuality was socially unacceptable, the protagonist Ludwik (a university graduate) left Poland in 1981 to live in the United States of America. And he remembers what it was like back then in Poland, where he went to the agricultural camp (which was mandatory for college graduation). At the camp, he met Janusz, who would soon become his lover. After the camp, Ludwik decided to go to a lake district with Janusz. They finally arrived at the lake district, and stayed by the lake for some days after pitching their tent. During their stay, they made love with each other.

In this part, I wonder what "so much" means. Does it mean perhaps the narrator felt that there was so much desire that he would not be able to grasp it (fulfill it) forever? Or would that mean he felt the concept of love was so grand that he thought he would not be able to possess it? Or is it probably a talk about possessing one’s partner, that one might never possess the other…?

I am an English learner from South Korea, so thank you for your patience in advance as I may not know obvious things. I would very much appreciate your help. 🙂
