As explained in the Outline of Devotional Sex, a Princess has the power to control all sensual and sexual activities. As well as making things happen, she can use this power to ensure that things go no further, and to end activities.
 
 
A weak Devotional Dynamic occurs when, even though a couple have agreed to practice Devotional Sex, one or both of them doubts that Princess Power will always apply.

The Princess might not feel confident that her Knight really will do what she says, that he will stop an activity when she says, and that he will accept that things will go no further than she wishes.

The Knight may have agreed to try Devotional Sex yet still be unsure if he is able to keep to this commitment.

Note that when you first try Devotional Sex the Devotional Dynamic will be weak because it will take a little practical experience for you both to feel comfortable in your new roles.
 
 
A moderate Devotional Dynamic occurs when both the Princess and her Knight know that Princess Power is real because they are sure of their own and their partner's commitment to practicing Devotional Sex.

When first learning Devotional Sex this will only occur during erotic activities. Both partners will play their role, and know that the rules will apply, but they will not yet have reached the stage where the roles feel natural.

Once the couple are living Devotional Sex a moderate dynamic continues even when the Knight is not aroused. His wish to continue practicing Devotional Sex means that he will still obey his Princess at such times, but primarily out of a sense of duty.
 
 
A strong Devotional Dynamic occurs when both the Princess and her Knight feel that Princess Power is real.

For a Princess this means that during sexual activity she feels relaxed and comfortable in the belief that nothing further need happen. She is relaxed about getting her Knight aroused because she can say "that's enough for now" at any time. Her freedom to tease can be lots of fun for both her and her Knight.

And if while enjoying just a cuddle her Knight becomes aroused, she can accept his arousal because she does not feel any pressure to respond.

Of course a strong Devotional Dynamic is also used by a Princess to have lots of sexual and sensual fun.

A few Knights will be naturally submissive and are thus able to feel a strong Devotional Dynamic even when their erotic energy is low. But for most Knights their feeling a strong Devotional Dynamic will be energized by their higher than usual erotic energy.

Though a Knight may be very aroused, his strong belief that Princess Power is real means that it is relatively easy for him to obey his Princess's wishes.
 
 
Without any Devotional Dynamic in place a male who is moderately aroused will want sex and will usually try to steer the activity in a direction that enables him to obtain it.

Within a moderate Devotional Dynamic, a moderately aroused Knight will still want sex, but will obey his Princess because that is what he has agreed to do.

Within a strong Devotional Dynamic even a highly aroused Knight will obey his Princess because it feels normal and natural for him to do so.

Normally, a woman who does not want sex and who is with a moderately aroused man will try to cool off his erotic energy.

In Devotional Sex a Princess can instead do something that increases the Devotional Dynamic. Though this may make her Knight more aroused, it will then feel more natural to both partners for the Princess to determine what happens next.

This is why, even when using Devotional Dating on a first date or with a Devotional Friend, it can work extremely well for a Princess to say "Reveal" and for the couple to spend some time practicing Affirmation. Even though the Knight's nudity increases the sexual tension, his being nude while his Princess remains dressed strengthens what might otherwise be a weak Devotional Dynamic. And this stronger dynamic makes it easier for the Princess to ensure that activities never go any further than she wishes.

The Display command is another good way to strengthen the dynamic. The Princess feels her power strongly when she says "Display". But the strength of her power is most apparent when she ends this activity and tells her Knight to sit down (either at her feet, or on a nearby chair).

In a Devotional Relationship, if a Knight is horny and not well behaved, some use of Affirmation and Display can restore the balance and enable the Princess to re-assert control.
