By making prolonged eye contact, you can strip a person naked, figuratively of course. Sex in the dark is out. Not unless the dark can be used to enhance other senses. This is not an age of innocence. It's an age of intelligence and women's freedom.
Women deserve to be seen.
And if the hero can see the heroine, she can see him, too. And where an aroused male form is involved, there's always a lot of exciting things to see. I enjoy showing the excitement. Romance should not be shy and sweet. Rich or poor, pretty or plain, dynamic or withdrawn, the hero and heroine have to be sexually attracted to each other.
