Cleaning Concerns: Soap vs. Water for Penis and Semen Hygiene - Urology

What are the cleaning issues related to the penis and semen?


Hello, doctor.
I would like to ask a few questions.

1.
Regardless of whether I masturbate or not, I have always had the habit of using soap to wash during my daily showers.
However, I've read online that using soap may be harmful to the body, so is it sufficient to just rinse with water? Especially on days when I masturbate, won't that leave me unclean?
2.
If semen accidentally gets on my underwear or other clothing, it seems that even washing it in the washing machine doesn't completely remove it; it still appears shiny.
What is that, and does it require multiple washes to come out, or is there a special method needed to clean it effectively? Thank you, doctor.

Hello: 1) Rinsing with clean water is acceptable, and using soap or body wash is also fine, but avoid excessive cleaning and choose products that are suitable for you.
Using just clean water will certainly not leave you unclean.
2) Regarding the material of the underwear, a typical washing machine cycle lasts several minutes, so it is unlikely that any residue would remain.
Wishing you good health.

When it comes to personal hygiene, particularly regarding the genital area, there are several important considerations to keep in mind. Your questions about the use of soap versus water for cleaning the penis and semen hygiene are quite common, and I'll address them in detail.

1. Soap vs. Water for Cleaning: It's generally recommended to use mild soap and water for cleaning the genital area. While some sources suggest that using soap can be harsh and may disrupt the natural balance of bacteria and pH levels, it is important to note that proper hygiene is crucial to prevent infections. If you are concerned about irritation, you might consider using a gentle, fragrance-free soap specifically designed for sensitive skin. For daily cleaning, rinsing with warm water is often sufficient, especially if you are not engaging in activities that lead to excessive sweating or dirt accumulation. On days when you have masturbated, it is still advisable to wash with soap and water to remove any bodily fluids and maintain cleanliness.
2. Cleaning Semen Stains: When it comes to semen stains on clothing, it is important to act quickly. Semen can leave a protein-based stain that may appear shiny or bright if not treated properly. Washing the stained clothing in cold water first can help prevent the stain from setting. After rinsing, you can use a regular laundry detergent to wash the item in the washing machine. If the stain persists after the first wash, you might want to treat it with a stain remover specifically designed for protein stains before washing again. Avoid using hot water initially, as heat can set the stain, making it more difficult to remove.

In summary, maintaining proper hygiene in the genital area is essential for overall health. Using a mild soap and water is generally safe and effective, especially after activities like masturbation. For semen stains on clothing, prompt treatment with cold water and appropriate detergents can help ensure they are removed effectively. If you have any specific concerns about irritation or persistent stains, consulting a healthcare professional or dermatologist may provide additional personalized guidance.
