Hello guys!

This is my first post ever here. Just registered 15 minutes ago after looking through a number of forums trying to find a scenario similar to mine.
Anyway, I (male) have had this best friend for about 2 years now, whom I really feel comfortable around. He goes to the same high school as I do, but not in the same class so we usually just hang out after school and on weekends. Hence, we don't have many mutual friends in school. Whenever we hang out what we usually do is watch a few movies/play some video games, and then stay over the night. We don't mind hugging or leaning towards each other or in general being intimate with each other, and whenever he stays over at my place we both sleep in the same extendable couch. Neither of us make a big deal out of it and it seems we both just enjoy being close to each other. However, being this close to him have gotten me thinking, since I feel so comfortable around him I would like to express my feelings for him in more passionate manners. I do not consider myself to be homosexual, which makes this situation so much more complicated. We are so close that I worry that I might misinterpret my feelings for him as romance instead of bromance.

Have any of you felt this way about a close friend, and if so, what did you do? Would it be weird if I tried to be more intimate with him (more frequent, passionate hugging, sleeping next to each other, possibly kissing etc)?
