Sir I masturbate with an iron made round thing which had a hole in the middle. I pushed in my penis inside there and continued masturbation. I used my saliva from mouth to make it smother. After masturbating I noticed it was rusted. That red thing junk type on iron. Can the rust get into my urethra or inside and make any damage? I am a 14 years old boy. Please sir. Can you tell me what to do. I am from west bengal.
