Is it normal for friend to do questionable things with me?

I'm 28 and he's 23 and I met him 2 years ago.

He tried licking my friend's ear as a joke when we first met.

One of his first conversations with me was him talking about circumcision and him basically asking me if I was.

When I went to his house, he talked about how he tells girls he has a small penis, but then said it's really like 8.25". I figured the guy was just curious and told him I was just average to which he quickly changed the subject. I also told him about a friend that wanted to give me a bj and he was like don't do it, I wouldn't let you give me a bj! But I didn't do it anyway.

That night we were in his room and he told me to turn my head because he had to get changed which he says he doesn't wear underwear to bed. I was like ok and turned my head while he put on pajama pants. I thought this was odd that he was getting naked in front of me instead of changing in a bathroom when we just met.

Later on I noticed he was playing with himself and maybe even masturbating under a thin blanket and would occasionally turn towards me with his eyes closed. I ended up calling it a night since it was late and I was nervous about staying over and he seemed upset, but I promised him that I was his friend.

Fast forward a few weeks and I'm over his house in his living room while he's showering upstairs. He came downstairs which he bypassed his bedroom and only had a towel on and he proceeded to get dressed under the towel in front of me. I thought, okkkkkk, why didn't he change in his room, does he want me to see him naked?

However, he always kept playing with himself or probably masturbating under a blanket every time I was over. He also always made it a point to always change under a towel in front of me. Normal?

Whenever we go to the movies, he's always leaning towards me and nudging me and always has his arm against my arm. I never thought anything of it until some of the stuff below happened.

So the second time that he stayed over my house, he was like, oh good we get to sleep in your bed since the first time we slept on the floor due to being in the process of moving. Usually when friends stayed over they would just sleep on the floor. But I noticed whenever we stayed in the same bed, I would wake up with him kind of breathing hard and the bed shaking a bit. I'm pretty sure I saw his arm moving, but I'm not positive. But I suppose it could be normalish to be comfortable enough to sleep in the same bed. Masturbating, not so sure if he was or if it would be normal.

The next few times that we slept over I started to wonder if he might have liked me more than a friend and possibly was throwing signs out. I woke up once and when I moved away from the edge of the bed I found out he was spooned behind me and I came into contact with him which he got an erection against me immediately. He stayed there for about a minute or three and turned the other way.

Then another time I woke up to him cuddled up to me and had his head on my chest. Then I woke up to him leaning his back against me and I could've sworn he was masturbating. Then he turned and swung his hand and briefly touched my crotch. The last time he stayed over I woke up with his arm across my chest and he sort of had his hand on my face. He's avoided staying over and inviting me over since then. But he says it's just a temporary thing until he feels like staying over or inviting me over. Again, I'm not sure if people do any of this in their sleep or if he was awake.

All throughout this I never brought any of it up and I never did anything back.

I'm not sure if what he does is normal, curious, gay/bi, or just straight and not normal. Being bi myself, which I'm pretty sure he knows, I wouldn't mind either way.
