Writing a romance novel? Well, then your heroinne had BETTER be a fiery, young, attractive, pert, independent woman who, nevertheless, falls in love with a rugged womanizer. The heroinne must be in a terrible position, such as an arranged marriage, and she won't ever just run away, or say NO WAY, that would be boring.
The hero, of course, is rugged and muscular. He runs with the wolves and is an untamed total beast. Also, his family jewels are always, ALWAYS 'impressive'.
The heroinne will tame the wild beast of a hero and though he seems to be an absolute prat, they will make love and live happily ever after. Oh, and the heroinne won't have to go through her arranged marriage after all--change of plans.
Also, it is fashionable for a thin, intelligent suitor to get pummeled by the brawny hero. That shows what a great guy he is.
And this pert, young, independent woman won't mind falling in love with a grunting, dirty womanizer. After all, making things in character is STOOPID!! 3nodding
