Him. I NEED OPINIONS PLEASE HELP

Alright so there was this guy who I had a serious crush on and I actually confessed but be turned me down and said he had a girlfriend well flash into last night and he sent me a pic on Snapchat (sc) and it was just all black with a hey in the middle. I wanted to know if it was to start a streak and I asked and he quickly replied “no, can I ask you something but it has to stay between you and I?” And l just went along and said sure. He then proceeded to ask me for nudes. Here’s the thing I told him I wouldn’t send him nudes because I know what types of things can happen to your reputations they get leaked so I didn’t. I then said “do you even remember who I am” and he said “yeah that’s why I sent you this” and I asked him to describe what I looked like and it was pretty spot on so I just went along and told him that it was rude of him to reject me and then ask for nudes a few months later. He said that he knew but there was a specific reason. So I listened. He said his girlfriend broke it off with him a while after my rejection and that he’d been thinking of me. He said he wanted to be in a relationship but wanted nudes because 1. He was horny 2.because he wanted to know what I looked like in case we dated so he could imagine me. Which I think is bull but he did sent me a lot of nudes and videos which I guess I kinda liked and he told me he didn’t ask anyone else for nudes. He was texting back really fast and it didn’t seem like he left the chat. I could understand that he could just be using me and everything but we’re going to be going to the same school next year and I feel like if it was him just using me he wouldn’t of done it because that would make school awkward. He also is known to be a really kind hearted guy he treats everyone with respect and is just really a nice admirable guy. He also told me that he’s loyal and that was why he rejected me. As in because he had a girlfriend his automatic response was to say he had a girlfriend. I need help and someone else’s point of view please help.
