Metrosexual, homosexual... does it really matter?

I was waiting around outside work the other day, just stood against a wall really excited about being ten minutes away from another gruelling shift. So I simply stood back and watched people pass me by, which was quite fun actually. I was also having a good listen to the conversations of the passers by too.
One conversation between a really, really pretty girl and her not quite as pretty companion really made me snigger, as well as provoking me to write this blog.
The very, very pretty girl said: "Yeah well he is really sexy."
The not as pretty girl replied: "And he was smiling at you all night."
The very, very pretty girl then said: "But he's so smartly dressed and definitely gay!"
Then they both laughed quite a lot.
So here's me laughing and thinking that if all guys that dressed smartly were gay, there just wouldn't be enough heterosexual totty to go around... but I know this isn't true, but it definitely got me thinking.
So I carried on watching people walking by, but disregarded any women walking by and just zoomed in on all men, any age, any size and tried to guess whether by their dress sense they were simply the new and modern 'metrosexual' male that people bang on about or homosexual. Not that I minded which one they were.
I saw middle aged men in really modern suits, with the slim trousers and ties to match, with the long, pointy shoes. Men that weren't quite as sexy as George Clooney, but definitely as well presented. I came to the conclusion they were all heterosexual, just very scared about getting old and masking it with such a modern style.
I saw many men that welcomed the true 'metrosexual' style. They were young professional type men, with pink and ever so silky shirts, tight trousers, shoulder bags, fake tan and immaculate hair. In other words, the true definition of the metrosexual male. The men who are heterosexual but gorgeous, toned, immaculate, dressed in designer gear, had disposable income and used it in a way to pamper themselves... very vain too... why not if you look good eh?
I saw one guy who really was quite an enigma to me. He was tall, he reminded me of a scruffy surfer type but quite sexy at the same time. Anyway, he was tall, with long, curly, black hair and quite big, brown eyes and quite a pretty smile. He looked really masculine, with the exception of the tight, purple shirt and hairless chest. So I was really confused about him, whether he was simply metrosexual or homosexual... until ten hours later, I realised he had the most stunningly pretty girl holding his hand- that I could only assume was his girlfriend.
The point I'm trying to make is that there are so many gorgeous men out there with their own unique and most cases extremely modern styles. And if I decided that every guy out there who looked slightly 'camp' because he had a pristine appearance was homosexual and therefore unavailable, I'd severely restrict myself in life.
A person's sexuality, or even what you assume their sexuality is, shouldn't get in the way of getting to know them whether a relationship will or will not be on the horizon, because friendship is a thousand times better and less complicated anyway!
Also, if a guy has decided to follow the metrosexual trend and start wearing pink and sporting really pointy shoes, then that's them trying to impress all the attractive and modern females out there - not because he's trying to bag a bloke, so by assuming because he may look slightly too good to be true that he's gay is just shooting yourself in the foot because he could be straight and single! Bargain!
