Fell in love again with a straight friend, so is he gay or not?

For the third time, I fell in love again, with a straight friend. I know for myself that I am gay ever since I was a child but I'm still hiding it from (everyone). But I think some people know it, because of how I act and talk. Being gay is still an issue here in our country (Philippines) since 90% of the people here are very religious.So his name is Carl and I know that he's super straight and he's a college friend. He plays tennis, basketball and loves going to the gym. I've known him for four semesters now and I think we're good friends. I don't know if he knows that I'm gay but he's showing me some clues (like one time when we were eating an ice cream, he joked that I should swallow the whole cone because it is what I am good at).We both love watching TV shows, he also watches How To Get Away With Murder which made me think that he's gay or bi. I know that this is not a good basis, not just because there are gay couples in that show that doesn't mean that he's already gay by watching it. But he watches every episode of it right after it releases unlike other tv shows that I know that he also watches. Also I saw a copy of Magic Mike in his laptop (oops). In one of our class together where our seats are just like one mm away he always keeps on moving his shoulders and body towards me which makes me aroused everytime in that class lol. But I think he's just doing it because it's always cold in that room because of the aircondition. But why would he do that?
