Vagina size

When a guy tells you “I can tell you’re not used to guys my size” (something along those lines)...what does mean? I felt offended. But his was very small though and skinny. Was he just too little for me? Or was he implying that I’m some type of ran through whore? Because I’m definitely not that. Is it possible to be to “big” or “loose” down there? Or will guys just say anything to damage you to make them feel better? Because either way he came and I didn’t 🧐. Help me understand this. What are some offensive things you heard before, during or after sex.
