-- It is not recommended to do this to avoid injury.
I started masturbating since sixth grade, and I have seen other friends do it naturally; I'm the only one who experiences this.
Additionally, after ejaculation, I feel a slight heaviness and fatigue in that area for a short period.
Is there something wrong with my body? -- This is a common phenomenon.
If it lasts too long, such as for several hours, please try to reduce the duration of your activities.
Wishing you good health.

More Info

The phenomenon you're experiencing during masturbation, where your testicles move upward, is quite common and can be attributed to several physiological factors. First, it's important to understand that the testicles are not just suspended freely; they are connected to the body by the spermatic cord, which contains nerves, blood vessels, and the vas deferens. The movement of the testicles is largely controlled by the cremaster muscle, which is responsible for raising and lowering the testicles in response to various stimuli, including temperature changes and sexual arousal.

During sexual arousal and masturbation, the cremaster muscle contracts, pulling the testicles closer to the body. This is a natural reflex that helps regulate temperature for optimal sperm production and can also be a response to the excitement and stimulation of sexual activity. The upward movement of the testicles can also be influenced by the position of your body and the way you are stimulating yourself. If you are using a specific grip or technique, it may inadvertently cause the testicles to move in a certain direction.

Regarding the sensation of fatigue or heaviness in the genital area after ejaculation, this is also a normal response. After orgasm, the body goes through a refractory period, during which the muscles in the pelvic region may feel fatigued or tense. This is due to the intense muscular contractions that occur during ejaculation, which can lead to temporary feelings of discomfort or heaviness.

It's worth noting that variations in how individuals experience masturbation and the accompanying sensations can be quite normal. If you find that your testicles are moving in a way that is painful or if you experience any unusual symptoms, such as swelling, persistent pain, or changes in the appearance of your testicles, it would be wise to consult a healthcare professional. They can provide a thorough examination and address any concerns you may have.

In summary, the upward movement of your testicles during masturbation is a normal physiological response controlled by the cremaster muscle. The feelings of fatigue or heaviness afterward are also typical and should not be a cause for concern unless accompanied by other troubling symptoms. If you have further worries about your sexual health or anatomy, don't hesitate to reach out to a healthcare provider for personalized advice and reassurance.
