Alpha hero goes on a date

Here’s a man able to meet life and death challenges with the cool and quickness of a James Bond, but frets and obsesses over a date. Note: there is a natural humor to this, but it so human. Many men and women go into a fit of histrionics when preparing for a date. They’ll try on different outfits. Brush their hair and then brush it again, sure that one loose strand will lead to rejection. He’ll cut himself shaving. Ruined! They’ll practice things to say, etc.
You might think I’m talking about a metro-sexual guy. Nope. Here’s a chance to inject a touch of flaw, excitement, show him as human, as interested. It is, after all, a life and death situation. Humans need love to survive, to be fully human. No less so, the alpha hero. Just don’t expect him to be in command of himself at home preparing, or maybe on the date. He’ll put his life on the line, but when it comes to making life happen (well, not usually on a first date) he’s a klutz (or somewhere in between James Bond and Barney Fife). He could appear normal, but inside he’s a tangle of insecurities. Or perhaps his stage fright disappears as he gains confidence and takes in the beauty that sits across from him. He’s a lucky man.

Elementary: Supply and Demand 101

Supply and demand can be applied to romance. It’s true that there is approximately the same number of men and women in the world thanks to the magic of the laws of nature. It is also true that long term profitability business models seek balance between buyers and sellers. Men and women, IMO, seek balance when they hunt for a mate. For the sake of simplicity, let’s say the entire planet has ten womern and ten men not yet pared off and they’re having a party. They may fight over the same person, but it is more likely they’ll consider their own strengths and weaknesses plus that of their group of ten. Take it a step further and they’ll consider the group and individual needs of all twenty. It’s not perfect. People make mistakes. The intent, for those thoughtful enough, is to consider, perhaps at an elemental level, the survival of the species.
This is why I say: Something else is going on here. Some will reach the gut conclusion that one person in the other group was made for them. They’ll both know it when they look into each other’s eyes or have some other interaction. The other eighteen back off, recognizing this new force of nature.
What part mysticism plays in the laws of nature no one knows. You can call it, fate or they were meant for each other, or use the word soul mate. It may be a biological directive, the finger of God. Who knows. I guess I’m saying that if you are writing a normal as opposed to a paranormal romance don’t forget to sprinkle a little uncertainty into the love equation. God (or nature) knows. We don’t (too well).
Examples of how you handled this are much appreciated.
I’ll give an example from one of my stories. In the story, the heroine is in a bar and walks over to a complete stranger and plants a kiss on him (that they’ll never forget). She walks away.
