In general I would say no for me. Not that I have anything against it, just that it hasn't worked out that way in my life. However, I have one that I've been friends with for 8 years now, that I am more than a little attracted to in multiple ways, but she's married and that's not ground I wish to tread on. That said, I'd rather have her in my life as an awesome friend, than not at all.
I noticed a couple fellas brought up having gay friends as well. Well, cliche or not, I have many of them. I live in a city where 40% of the male population swings that way, and it'd be pretty limiting to not have friends of that sort.
