Can someone please explain the brain of a 21 year old male to me?

I'm seeing this man who is twenty-one years old. As an eighteen year old girl I'm just curious as to what goes on in his mind? If you're a male around this age could you give me some insights?

I'm pretty sure he's not just in it for the sex, we spend quite a bit of time together with no expectation for sex although it's great fun.
