One problem all authors face is writing 3D characters of the opposite sex. Some manage it better than others, some fail dismally. However, a readthrough of some psychology texts will help as will a close observation of people.
The trouble with those two, however, is finding the right psychology text and not getting arrested, propositioned or punched while you stare at people.
With that in mind, here are a few pointers about men, an area where I have some specialist knowledge.
Men think slower about emotions than women as well as less often. It's not that men can't be emotional as any brief look at a football game will show. Nor is it that they focus on negative ones, you only have to look at a father/child relationship to see that. They just take their time.
Male emotions are as deep as those of women, just not so apparent. Some of this is genetics, but it's also due to upbringing and society. When confronted with looking at his emotions a man will take days to work it out, but will be thinking rather than talking and doing it subconsciously most of that time. Oftentimes he will also have trouble finding the correct words.
This can make for some dramatic and comedic scenes and can be seen in most good books/films/tv shows.
Men share silence. They can say nothing of any value to each other yet, after an hour, feel like lifelong friends. Maybe it's instinct, maybe it's an unknown hidden attribute of men, but they can spend time in another's company and know them well without actually telling each other anything about themselves.
It's also why, after years of friendship, a man can say something and his friends be surprised. Men share time not (many) words.
Yet another way to build tensions between two male characters or a man and a woman.
Men do. If they want to show love they'll buy something or work harder at the office to get more money. They'll provide more things. Saying the words isn't as important and they can get surprised when it seems important to a woman.
As with all rules there are exceptions. A man raised in an all-female household will be more aware than one raised in an all-male household. Their genetic makeup and upbringing will change these attributes to a greater or lesser degree. In short, these are guidelines not hard and fast rules.
With that in mind I leave you with this perfect example.
That just leaves me to ask a question: Will somebody please explain women to me?
And on that note, I bid you adieu and I shall see you on Friday.
