It's important to maintain personal hygiene as your body changes during your teenage years. If you're asking about using a tissue during private moments, here's a clear and respectful guide:

• Use tissues carefully: When you feel the need to clean up after touching yourself, having tissues handy is helpful.
• Be gentle: Use soft tissues to avoid irritation on your skin.
• Dispose properly: After use, wrap the tissue and throw it in a trash bin to keep your environment clean and hygienic.
• Wash your hands: Always wash your hands thoroughly with soap and water afterwards to prevent germs.

Remember, understanding your body is a natural part of growing up. If you have more questions about your body or personal care, consider talking to a trusted adult or healthcare professional for advice.
