It's great that you want to approach this topic respectfully and responsibly. When it comes to discussing masturbation with a friend, especially at your age, it's important to remember a few key points:

• Respect Boundaries: Everyone has their own comfort level with topics like this. If your friend asks questions, it's okay to share general information, but avoid getting too personal or explicit.
• Use Reliable Information: Providing accurate, age-appropriate information is important. Masturbation is a normal and natural way to explore one's body.

Preparing for Ejaculation:

When someone gets close to ejaculation, it's their body's way of releasing semen. Some key points to share are:

• It's a normal biological process during sexual arousal.
• It usually leads to a feeling of pleasure and relaxation.
• It can happen anytime after puberty begins, which often happens around age 11-14.

Cleaning Up:

After ejaculation, it's important to clean up to maintain good hygiene. Suggestions include:

• Use tissues, toilet paper, or a clean cloth to wipe away semen.
• Wash hands thoroughly with soap and water afterward.
• If semen gets on clothes or bedding, wash them as soon as possible.

Remember, it’s okay to learn about your body and to ask questions. If you or your friend ever feel unsure, it’s a good idea to talk with a trusted adult, like a parent or a school counselor, who can provide helpful information.
