I'm a man. My opinion is that if you're writing romance, then you're over thinking it. I have read over 200 romance novels and not one of them has a male lead that acts like a real guy. Hehehe. There are alot of authors who are very good writers, but lets face it, the romance genre wouldn't be so successful if the guys were like real life pricks you know already. *lol* I'm serious though. The male heroes are impossible men... real men have not a chance to compare and its one of several reasons why most men dont read romance. They can't relate to the hero and feel ashamed for not living up to the impossible standards set by them.
In short, the men aren't like real men in romance, so don't stress over it all that much. Rough estimates show that romance readers are less than 5% male. Of us men who do read it, we already know your hero won't be like a real man. If men acted like that, women wouldn't be reading, and instead would be living romance. Hehehe
IMHO
I agree with this (mostly). Not all men are pricks, but the majority do not act the way a romance hero does either. And I can say that having married one of the good guys. The way these guys think and act sometimes....well, not like any guy I have ever met. And between my hubby, guys I have dated, and the fact that most of my friends have been male, I think I know men ok. I have even read some stuff from my books to my hubby and he mostly laughs. But that is why women read romance, to escape the boredom of their lives. Even the sweetest, most adventurous, most romantic of real men can't compare to men in romances. And their is nothing wrong with that.
I think you should know your character, whether male or female, and be able to write them well. Don't think too hard about "Would a guy say this?" or "Would a woman really do that?" You don't have to write (stereo)typical men and women. Just write. If you are still unsure, I would try to get some male beta readers to give you some finer points about the male psyche. But you will have to remember that most men do not read romance, and probably won't like it anyway. You have to appeal to your reader, which in this genre, will be mostly women. What do you, as a woman, want from a man? How do you want him to act and think? But most importantly, men are human, just as much as woman. I think we mostly want the same things out of life.
Just my 2 cents
