Guy's Behavior

What are his intentions? is he into me? can you guys enlighten me?

There's someone I get along so well, and he's a very touchy person. We're comfortable with each other, so physical contact isn't an issue between us. We consider each other friends, but I've noticed that he's extra touchy with me compared to others. He often pinches my arms and waist or tickles my sides. He also puts his hands on my legs or thighs—sometimes squeeze them or smack them. He can't seem to go a day without doing these things. I don’t necessarily have a problem with it, but it does seem a bit unusual since his physical contact feels intentional, even when unnecessary. One time, I was sitting on a chair doing something on the computer and he suddenly was tickling my upper side thigh, around the glutes area and just smack em (that was really weird). Also, there was a time he randomly massages my shoulders and I just played along with it. Also, there was a time we were watching a movie while eating a popcorn and my fingers where covered with cheese powder. A friend of mine called and while I was on call, that dude just let his intrusive thoughts win- The dude legit tried to bite my fingers covered in cheese—my fingers were so close to being inside his mouth. I literally smacked his arms. In addition, dude was hella flirty and suggestive to the point that I can't even process what he was saying. One time, he asked me to check whether he's infertile or not, how am I supposed to do that? On the other hand, aside from him being touchy, our conversations and topics are usually deep. It revolved around how we see relationships, what we think of it, family, kids, family dynamics etc. One time, he asked me what it takes for a man to date me. Also, asking my opinions on engagement rings, would I marry a mama's boy, whether should I stay with my partner if things are not working out especially when there are kids already, how many children do I prefer, would I rather marry someone rich and not work, or marry someone and still have to work, and etc.

There are times in our convos where he asked me if am I gonna leave my future husband if I found out he's infertile, he noted that it's legal to leave and also, he said that I just found out about it after getting married, will I leave the guy? I just said no and explained why... Then, he just randomly said about what if he's infertile (referring to himself).

There are times where he talks about his life, he's issues, his past relationships, his struggles, his unfulfilled dreams and I'm just there actively listening. Sometimes, he's telling me that I should not hold back. And even asked me what it is like to be loved by me.
