Are we supposed to believe that Harry and Sally were once satisfied with friendship, or that they always harbored romantic feelings? Option 2 seems more likely: Their friendship was actually a courtship all along. Like Harry and Sally's friends, the viewer expects and wants the couple to get together. And even first-time viewers with the most basic understanding of plotting must realize that, narratively, romance is inevitable.
The upshot is that truly platonic cross-sex friendships appear to be easier in real life than in Hollywood movies. Link
In other words, yes, I'm talking about a good, close friend. Such friendships are rare between genders, but heck, they're rare within one gender too.
Ok, so those female friends that you have no romantic feelings for, are you sure they feel the same way? If not, then it's not completely platonic.
I dunno, maybe my definition of friend is more intimate. I have a large group of acquaintances that I would, for example, invite to a large party, or invite out with a group and yes, there are females there that I can say I don't have romantic feelings for but I don't call them friends in my mind although I might say, "yes" if someone asked if they were my friend.
Friends are people I'm excited to hang out with even one on one and that make me laugh and that I have fun with. I can't see how I wouldn't be romantically attracted to those women. I just don't understand how could anyone not be?
I've also got female friends toward whom I have both friendly feelings and sexual attraction, but I keep the attraction to myself for one reason or another (one of us is in a relationship, she's not into guys, she's made it clear that she's not interested, etc.). I think that's more common, but true platonic friendship is absolutely possible.
