I've already stated my opinion on this, but I'll elaborate a bit. I have a couple very good/close male friends. They are not shallow relationships. We have meaningful talks often. When we actually lived by each other we hung out. As often or more often than some of my female friends. One in particular, I would say, was a very good friend to me indeed. He was the one person who really helped me out and even drove a bed out to me when I was a huge pregnant ass and didn't have anything to sleep on. He did it out of good will and because he enjoys our friendship, not because he was trying to get in my pants. I'm only sharing this to help illustrate the level of our friendship. I talked him out of suicide once as well.
I am married. My husband isn't jealous of him. He isn't jealous of my husband. There are no awkward secret hidden feelings.
I suppose I can agree with those saying that this sort of situation is an uncommon one. But to say that it is NEVER possible or that people who think it is are naive, is a flat out lie, because I've lived it personally. It is entirely possible. I had other male friends in the past and the situation was exactly the same. We could hang out alone in a room and play video games together even without there being any strange sexual tension from either end. We would hang out alone, or in a group. Just the same as any of my other friends. Someone before mentioned a more brotherly/sisterly sort of feel. It definitely sounds accurate to describe it that way to me, although I was raised an only child so I don't have a solid experiential basis for that myself.
In fact, as yet another example, one of my other male friends, was the ONLY one of my friends to actually show up for my court room "wedding". I invited 7 people. Everyone else had something else to do that was more important that day I guess. He and I have never had any weirdness either and I've known him since the 9th grade.
In my experience/observations, a persons "friends" are always going to be at a different connection level to their romantic partner. It's not even the same kettle of fish. You can have a deep connection with a friend and still have an even deeper connection with your lover.
