If you are in a sexless marriage due to her having low desire then Devotional Sex can change both of your lives for the better.
There are many definitions of a 'sexless marriage'. One is that sex happens 10 or fewer times per year. For this discussion I'll use that sex happens less than every two weeks with him wanting it to happen more often and her not wanting this. So this discussion will also be relevant for those who are not officially in a sexless marriage but don't have much sex.
One solution is to go to couples counseling with someone who specializes in sex. A counselor may define success as getting you back to 'normal' married sex with foreplay, then intercourse, happening about once a week. But this can fail to fix the biggest problem which is that the sex isn't a significant mutual pleasure for you both.
Using Devotional Sex to improve your sex life has similarities with many of the the things a counsellor will recommend. But it also has some big differences. The biggest difference is how you will judge success.
DevS isn't about how often you have intercourse, but the quality of your erotic intimacy - both the quality of the activities you do and the quality of the intimacy and connection you feel in your overall relationship.
DevS takes away for the focus on Joy (intercourse). Most couples who practice DevS don't have Joy most sessions. And 20% of those living DevS (ie always practicing it) don't have Joy at all! The couples who don't have Joy, perhaps surprisingly, have both him and her as happy overall with their Devotional Sex life as all the couples who do include Joy. This happens because the couple who don't have Joy gain enough pleasure and satisfaction from what they do to keep them both very or extremely happy.
The way a sexless marriage is talked about it carries the assumption that the problem is her lack of desire. But what is it that she doesn't desire? If the sex that you have been having for the last many years doesn't give her any pleasure, doesn't make her feel connected, and that doesn't turn her on, then her lack of desire is an appropriate response.
Where DevS excels is that it provides a new way of doing things where she can explore and discover what she enjoys, and as she starts to enjoy what is happening her desire naturally returns.
Before you can start Devotional Sex:
The first thing is for the man to read about DevS so that he understands how it will work. It is vital that he commits to giving this a go, and that when he is doing DevS that he keeps all his commitments. It's possible that she will quickly see the benefits of DevS and that you will both fairly quickly start to explore the joys of DevS together. Many have described this as a second honeymoon which is even better than the first. But at the other end of possibilities is that improvement will be a very slow process. Even if he is a perfect Knight she may sometimes take backward steps. And when this happens it is even more important that he maintains his role. If she is uncertain about all of this, and he breaks his commitments, then that may be enough for her to give up totally.
Note that part of how you progress with DevS will be ensuring that the Knight has realistic targets. So, for example, unless she jumps enthusiastically into her role, the Knight might still be able to masturbate and ejaculate when alone.
One of the joys of things improving slowly is that every small improvement becomes a big event. And enjoying the little progress you have made at each stage feels really significant. So he needs to be prepared to focus on the improvements and what is happening.
Long term DevS can only happen if you both feel that you are better off doing DevS than not, and that the rewards from DevS more than make up for the effort needed to keep things working. The rewards from practicing DevS are compared with what would happen if you went back to your normal.
When your normal is a sexless marriage, you may find that even if you don't get anywhere near the sex life of other couples who practice DevS, the rewards and pleasures of what you do enjoy are so much better than your old normal that you are both very happy to have at least made a significant improvement.
Getting her onboard
Devotional Sex is all about building and maintaining erotic intimacy. 'Intimacy' is not just another way of saying intercourse. As said above, it's possible that Joy won't happen. And what does happen will be done in a very different way from before.
So DevS requires him to be so keen to restore erotic intimacy that he will become her Knight and let her decide what happens and when.
And most importantly in this situation, it requires her to want to restore and then enjoy erotic intimacy.
DevS is a mindset where lack of erotic intimacy in a relationship leaves a massive emptiness to the relationship. Note that having conventional sex once a week where she just lets it happen and wants it over quickly is just her letting him use her for masturbation. So there is no erotic intimacy.
Unfortunately some relationships will have got to the stage where she has no interest in restoring erotic intimacy. Perhaps as the difference between erotic intimacy and sexual activity is better understood, she will eventually agree that it would be good to try DevS. But DevS will only work if she is open to enjoying your first explorations.
How things will be different will be shown later when I say how DevS can get started when she is very much not wanting to go back to the old way of having sex but is open to exploring erotic intimacy.
If she has no interest in trying to restore erotic intimacy I recommend that you seek marriage counselling.
The next posts in this topic will be on how to best introduce the idea of DevS and erotic intimacy to her. Later posts will look at the many ways that you can both start to explore this new dynamic.
This has been written fairly quickly. I may go back and edit this.
