Many 18-year-old men notice that the intense pleasure leading up to orgasm feels different from the sensation at the moment of ejaculation and immediately afterward. This is a normal physiological response.

Understanding the Two Phases of Male Orgasm

• Emission phase: Sperm and semen move into the urethra. This builds intense pleasure and pressure.
• Expulsion phase: Rhythmic contractions eject semen. The peak pleasure is brief, followed by a rapid drop in arousal.

Why Sensation Changes After Ejaculation

During the refractory period, your body releases hormones like prolactin and oxytocin that lower sexual arousal almost instantly. The penis becomes highly sensitive or even uncomfortable to touch, so continued stimulation (such as continuing to use a masturbator) no longer feels pleasurable.

Tips for Comfort

• Stop stimulation immediately after ejaculation to avoid overstimulation.
• Gently clean the masturbator and yourself with mild soap and warm water.
• Allow your body to rest during the refractory period, which can last from minutes to over an hour in young adults.

This pattern is completely normal and varies between people. If you experience pain, prolonged discomfort, or other concerns, consult a healthcare professional.
