Is it possible for females to be strictly friends with males?

I am friends with a single guy from church who is 5 years older than I am. Despite we both respect one another’s boundaries and such and both know we are not interested in each other romantically, he believes that its possible for a male/female to be strictly friends, is he correct? Or am I just being naive and ignorant? And also I was told that its not appropriate to have a guy friend to visit your place even if we are just friends is that true?
