please help me:( I can't figure out what any of this means :(

Here it goes. Okay so there are two buses that go out to the country to pick the kids up who live there. One of the buses broke down the other day so we have had to double up and the kids that usually ride the other bus have been on ours. Well, my crush rides that bus. It has been working out perfectly because I've been trying to find ways to talk to him and be around him more often and now we finally have 40 minutes each night together:) Except there is one problem. My BFF who rides my bus likes him too and she is all over him every night 🙄 But whatever, she is the least of my worries. He doesn't like her. So anyway, yesterday we were all riding and I was in one seat and he was across from me, and then my BFF was in front of me and another guy was across from her. We were all just hanging out and talking and my crush kept asking me things like he was trying to get to know me. And we were leaning into the aisle so we could all talk and he purposely kept sliding closer to me so that our legs were touching and our legs were tangled into each other's 😌 Something about him touching me and wanting to touch me made me just want to AHHHH!! And he had his bag on his lap and the other guys asked "why is that bag on your lap?" And my crush said that he was hiding a boner from me. I know he was kidding... but why would he even say that? Do you think he is attracted to me like that? But wait, there is more. So you know how our legs were tangled up together... well, my crush rubbed his knee against my leg to get my attention (low key) as he was still talking to everyone else. Is that a sign he likes me? Also, he asked me this. He asked if I ever have gotten a dick pic. I told him yes, I have gotten a few but none that mattered. So he said "did you like them?" And I said no because they were all random dick pics and I don't like random ones. So he said he understands why girls don't like them random. And then he asked if I've ever sent nudes. I told him That's none of his business but he could see in my eyes that I have so he said it's okay that I did and I told him that I do regret sending them. 

I need help figuring out what all this means!!! Does he like me? Or does he just want sex or nudes or whatever??? Please help. It would suck if the person I like the most just wanted to use me.
