How do I show him I love him?

I have a boyfriend, and he is honestly amazing. Perfect for me, really. Might be stupid of me to think it but I honestly think he’s the one. Recently I think he’s been dropping hints that he loves me. He said it once but it was over a call and I wasn’t entirely sure that I heard him right so I asked him to repeat himself and he said “I didn’t say anything.” I don’t know how to explain the other circumstance but basically I think he referenced being in love during a movie we were watching, but I wasn’t sure so I just kind of dropped it? I don’t know how to take hints. He always makes fun of me because before we dated, I had no idea that he liked me even though he did obvious things, like cuddling with me beneath a waterfall. Okay, yeah, that one makes me sound stupid, I know. But basically, he hasn’t said it, and regardless of whether he does or not, I want to show him that I love him in a manner that is so obvious that it’s the same as saying it. I’m the type of person that needs to receive love verbally- if you don’t come out and say it, I have no idea how you feel. As mentioned before, I can’t take a hint. But he’s the opposite. He likes being shown rather than told, and although my instincts are telling me to write something expressing my love for him, I know that that’s how I receive affection, not how he does.

tl;dr How do I show him I love him with a gesture, rather than something involving words?
