If your day to day life is one where you have to deal with stress, maybe you're a boss or supervisor, you could be one of those who has a subconscious mind taking care of you in your sexual desires. To deal with the stress, sometimes the subconscious mind comes out and you become very submissive, wanting to forget the stress of the day and let someone else make the decisions in your sex life.
In fact, it's quite common for this type of thing to happen. If you've never experienced submission, you should at least be able to think about how you'd like it to be, if you have submissive tendencies. Submission to you can really be whatever you want it to be. It can be as simple as a spanking, or maybe even some bondage and being forced to sexually service your partner. It can be what you read in stories, but it's a personal thing, so it could be nothing like what you have read in stories.
Writing about submission is difficult, if you don't have those feelings, or have never experienced it in a relationship. That's part of what happened with the Shades of Grey books. She had never experienced submission, nor had her husband experienced being a dom. So, her story line was really a romance novel, but she inserted bondage and punishment scenes in place of the romance scenes. They tried to experiment with implements, but neither of them really understood the nuances involved. She also had to make the dom living a troubled life, because she couldn't understand why a "normal" person would have sexual desires like that.
Of course, the average housewife loved it, just like they would love any other romance novel. But, anybody who had actually experienced the lifestyle, saw it as the crap it was.
The first paragraph is very, very true for a lot of people. As someone in that position, there are days when it would be very erotic and satisfying. Not every day, but some days.
