The case for slowness
Slowness in sex is usually presented as a matter of romance or consideration. It is neither. It is a description of how long it takes to fill tissue with blood, and the consequences of ignoring it are physical rather than emotional.
The advice to take more time is so familiar that it has stopped carrying information. It sounds like a preference, or a piece of etiquette, or a claim about what one sort of person likes. It is none of those. There is a specific physical process, it has a duration, and the duration is not negotiable by intention.
What is happening during the wait
When arousal begins, signals from the nervous system relax the smooth muscle lining the arteries that supply genital tissue. Those arteries widen, more blood arrives than drains away, and the tissue engorges. In a vulva this means the clitoris swells, including the internal crura and bulbs that make up most of its volume, the labia thicken and darken, and the vaginal walls become congested.
Two useful things follow from that congestion. Lubrication appears, because plasma is pushed through the vaginal wall as the tissue fills; there is no gland producing it on demand. And the vagina lengthens and the upper portion widens, a change usually described as tenting, which alters both comfort and sensation considerably.
None of that is instant. Filling tissue with blood takes time, and how much time varies between people and between days according to hydration, temperature, medication, cycle phase, stress and fatigue.
What rushing actually takes away
Three things, all concrete. Insufficient lubrication, because the fluid follows the blood flow that has not yet happened, which produces friction and the soreness that follows it. Insufficient tenting, so penetration reaches structures at an angle and a depth that would be comfortable later and is not comfortable now. And reduced sensitivity, because the tissue that carries most of the sensation has not yet swelled into position.
The cumulative version is worse than any single evening. A body that repeatedly experiences the same activity as uncomfortable begins to anticipate discomfort, and anticipation is one of the reliable brakes on the vascular response. The problem then presents as a loss of interest, which is a fair description of the symptom and a poor description of the cause.
Why the warm up cannot be accelerated
Intensity is not a substitute for time. Applying stronger stimulation to unaroused tissue does not speed the process up; the tissue is not yet in a state to receive it, and strong input on an unengorged clitoris is more likely to register as sharp or numbing than as pleasant. This is the anatomical reason described in the clitoris guide, and it is why the first ten minutes reward gentleness rather than effort.
What can be shortened is the runway before the runway. Arousal that begins hours earlier, in conversation, in anticipation, in a message during the afternoon, is genuinely further along by the evening. The clock does not have to start when clothes come off.
The asymmetry problem
Two bodies rarely warm up at the same rate, and the difference is frequently substantial. When one person is ready in two minutes and the other needs twenty, an unexamined default takes over: the pace is set by whoever is ready first, and the other person spends the session catching up, or quietly not catching up.
The correction is a single decision, made once rather than negotiated each time: the pace belongs to whoever needs longer. It takes almost nothing from the faster person, since arousal maintained for longer is not a hardship, and it changes the experience entirely for the other.
Slowness as a sensation, not a delay
There is a further argument that has nothing to do with preparation. Slow touch is a different sensation, not merely the same sensation stretched out. Nerve fibres responding to slow gentle stroking are a distinct population from those carrying fast pressure, and the sensation they produce has its own character.
Practically, this means slowness is worth doing even when nothing needs warming up. A pace slow enough to feel each pass gives the nervous system time to report detail rather than a summary, which is exactly the resource the exercise in body mapping depends on.
The short version
Start earlier and further back than seems necessary. Let the person who needs more time set the pace. Use lubricant rather than treating its absence as a verdict. And stop reading the first fifteen minutes as an obstacle between the beginning and the real thing, since physiologically that is where the real thing is being built. The companion note is pleasure as rest, and the mechanism sits in the body region.
