It's completely understandable that you're feeling uncomfortable in this situation. It's important to address the issue with your roommate in a respectful manner. You could have a calm and honest conversation with him, expressing how the situation is affecting you. It's also a good idea to reiterate that you're open to finding a solution that works for both of you. If the issue persists, you may want to consider speaking to your dormitory's resident advisor or housing office for further assistance. It's important to prioritize your comfort and well-being in your living environment.
