There's just one golden rule, namely: women need less clarity then men. Don't ask me why, just take my word for it.
So when editing portrait pictures of men increase the clarity and for women do exactly the opposite: decrease the clarity.
Let me show you two examples:
I guess for a woman, we're very much used to a soft skin. Whereas for men it's accepted to see more details of his skin.
Then again, in some cases you can ofcourse also decrease the clarity in a portrait of a man. Just to create another atmosphere. But let me tell you that if you do it the other way around: increase the clarity in a woman's portrait, the subject of your portrait might not be too pleased. Have a go and try it out on different portraits.
