Constantly repeating the same technique does not always produce the same results — and this is quite natural, since the body's sensitivity also depends on the hormonal cycle.
The influence of the cycle Fluctuations in estrogen and testosterone levels throughout the month directly affect genital sensitivity—many women report increased sensitivity near ovulation, and decreased sensitivity before menstruation.
The role of stress levels High cortisol levels (work stress, fatigue) directly reduce the activity of the parasympathetic nervous system, which changes the intensity and type of stimulation needed from day to day.
Why this is not a problem Consistent change means that the body is “alive” and responding to real physiological conditions—a fixed, unchanging response is actually rare.
A practical approach Each time, “listening” to what works on a particular day is much more effective than mechanically relying on previous experience.
