Does anyone have male friends you're comfortable with, and like them as a friend and not romantical?

A lot of people said girls and boys can't be close friends cause it's easy to fall in love at that point, but I dont really believe that, although i dont really have a prove, cause I have never had a male friend before until recently. I'm a girl and for a very long time I couldn't make a single male friend in my life. Even if I had one, we weren't close, and more like classmates or casual friends. But I met a guy recently and we have a lot of similarities and get along pretty well! Although I have to make an effort to think what to say to him, cause I dunno how guys think, so I always think how to talk without offending him or idk, I just want to make both of us comfortable. I'm very excited (sorry, he's just my first male friend) but kinda worried cause I dont want to mistake this "like" towards a friend for "like" romantically. Please, let me know your opinions;;; if ur a guy plz let me know yours too (⊙…⊙ ).. For now, idk how to appropriately treat a male friend.
