Thanks for writing in! It’s great that you’re paying attention to your body. However, know that everyone’s bodies are different. People may go through puberty at different ages or different speeds. At age fourteen, it’s possible your body hasn’t yet finished maturing. It’s also possible that it has. Try to love your body no matter what it looks like!
If you are concerned about your development, it’s a good idea to go see a medical professional. There are a few conditions that can cause small testicles; however, they are not reversible, so it’s still important to embrace yourself exactly as you are. Learn more about your family history, and make sure you have some trusted adults you can talk to. And know that people prefer all different types of bodies, too—your testicle size doesn’t mean you can’t experience a healthy, happy sexuality!
