Yes, it is possible.
The amount of guys/girls among my friends is pretty much fifty-fifty. I currently feel mildly attracted to maybe one of them, and have felt attracted to maybe one in four of the guys (my friend groups are very fluid, people fade in and out of focus all the time) but I know that this attraction often fades with time. Them getting a SO is the quickest way, heh. With most guys, it is as it is with girls to me: yes, I know that they are attractive in some way, but not to me. I can appreciate it, but I'm not interested.
I don't know if it is the same way the other way around, but I certainly hope so.
