That helps explain a familiar situation: a person is receiving technically “correct” stimulation, but pleasure is somehow limited. Part of their mind may be evaluating their body from the outside, replaying an argument, anticipating pain or tracking whether orgasm is arriving quickly enough.
But it would be equally mistaken to swing to the opposite extreme and say that “everything is psychological.” Physical stimulation, health, hormonal factors, medication, pain and physiology also matter.
Sexual experience emerges where body and context meet.
That is why a good lover is not necessarily the person who knows the greatest number of techniques. Sometimes it is the person who notices their partner has stopped being immersed in sensation and, instead of simply increasing the stimulation, asks, “Are you okay?”
Mechanics matter. They just operate inside the nervous system of a living person, not on a detached anatomical model.
