I'm gay, so GG. Although me and my lesbian friend did fake date for a month or two, solely to confuse the heck out of people.
But in all seriousness, there have been many guys, gay and straight, attractive and... Less so, whom I have been great 'just friends' with. In addition to that, the 'just friends' feel was on both sides, so no one was being friendzoned. When people say that men and women can't be just friends, it really seems like they think that men are savage beasts that care only for sex and have no standards whatsoever. Yeah, if they're attracted to each other they won't be 'just friends' but guys aren't attracted to every girl/guy that they come across.
