I believe they can. I have several male companions who I have no interest in having a romance with, or sleeping with.

Many people seem to struggle with this, and friends often question my close male relationships asking me why I'm not with them, could I ever see myself with them, and even "when are you going to marry him?''.

Harry says in the movie: "Maybe you get to a certain point in a relationship where it's just too late to have sex''. This point of Harry's I agree with.

I have some male friends, and even though I think they're cute, we are such good mates that I couldn't ever imagine being intimate with them, and I'm sure they feel the same about me ...at least I hope they do!

While I believe girls and guys can have amazing friendships without sex getting in the way, sometimes it does, and then sometimes as with Harry and Sally the best of mates can fall in love.

A couple of good friends of mine are the suburban version of Harry and Sally. They met through mutual acquaintances and started hanging out, with trips to the movies, the beach, dinners, even a road trip.

They spoke or texted each other every day, and were the last person to say goodnight to the other every night. After three months of being best mates, finally, they came together and fell in love ...awwww.

But it's not always hugs and roses when sex and friendship collide; sometimes it's a disaster. My friends were lucky. Even Harry and Sally had a rough patch and several yelling matches before they realised they were made for each other.

Experience has taught me that risking a friendship for a hook-up is very dangerous. Once that line has been crossed, there's no going back, and it can change everything.

With my best male friends, even if I did suddenly feel the urge, I wouldn't want to risk our friendship to start something that might not last. Unless I was fairly sure it was going to be an amazing love I was entering, I just couldn't take that risk.
