Here are corrected versions and a short explanation you can understand easily:
- Natural, one sentence: I have no fur, and my bare skin doesn't feel pain.
- Two short sentences: I have no fur. My bare skin doesn't feel pain.
- Short exclamation: I have no fur!
Notes:
- "No fur on me!" sounds informal and misses a clear subject and verb. It’s better to say "I have no fur."
- When you join two complete ideas in one sentence, put a comma before "and": "I have no fur, and my bare skin..."
- "My bare skin doesn't feel pain" is grammatically correct. "Doesn't" is short for "does not."
- Small meaning tip: skin itself doesn't feel pain—your nerves do. If you mean you don't feel pain through your skin, you could say "I don't feel pain in my bare skin."
Pick the version that sounds right for how you want to express it.
