Stimulation, in general, refers to how organisms perceive incoming stimuli. As such it is part of the stimulus-response mechanism. Simple organisms broadly react in three ways to stimulation: too little stimulation causes them to stagnate, too much to die from stress or inability to adapt, and a medium amount causes them to adapt and grow as they overcome it.
Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts.

[ 11 ] As sexual stimulation continues, orgasm begins, when the muscles of the pelvic floor , the vasa deferentia (between the testicles and the prostate), the seminal vesicles and the prostate gland itself may begin to contract in a way that forces ...
If these nerves do not detect stretching, the body determines perceives low blood pressure as a dangerous stimulus and signals are not sent, preventing the inhibition CNS action; blood vessels constrict and the heart rate increases, causing an increase in blood pressure in the body.
In this context, a distinction is made between the distal stimulus (the external, perceived object) and the proximal stimulus (the stimulation of sensory organs). [ 1 ] In perceptual psychology , a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis ...
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
Self-stimulatory behavior, also known as "stimming" [1] and self-stimulation, [2] is the repetition of physical movements, sounds, words, moving objects, or other behaviors. Stimming is a type of restricted and repetitive behavior (RRB). [ 3 ]
