It's time to like men again. Where shall we begin?
I have a personal preference for the backs of necks, because of the word nape, so lightly furred; which is different from the word scruff. But for most of us, especially the beginners, it's best to start with the feet and work up. To begin with the head and all it contains would be too suddenly painful. Then there's the navel, birth dimple, where we fell from the stem, something we have in common; you could look at it and say, 'He is also mortal.' But it may be too close for comfort to those belts and zippers which cause you such distress, and comfort is what you want. He's a carnivore, you're a vegetarian. That's what you have to get over.
