It appears that your concerns are about physiological development. It's important to keep in mind everyone's body is different and develops at its own pace. In your case, you are above average for your age or for men in general. While this might make you feel unique, you may experience some discomfort or practical issues because of size. For instance, you might have trouble finding the right size of condom which is important for safe sex. If you have questions or concerns about your body, it's always a good idea to consult with a healthcare professional. They can provide accurate information and reassure you about normal development. It may feel embarrassing to talk about this topic, but remember, they are there to help you. Also, you may want to try discussing this with a trusted adult in your life like your father or an older sibling. Try to remember that everyone's body is different and that's okay. There is no 'normal' size or shape of a body part that applies to everyone. Be comfortable in your own skin. Just remember the important steps to take for protection and safe sex.
