English not my first language

Long story short, was getting my dick sucked last night in my car and I have good size, so this chick while giving head asked me

What size is it?

Me: 2 inches

She started laughing and said what?

Me: maybe 3 (obviously being sarcastic)

Now she started laughing hard and told me shut up and kept sucking

Now I'm overthinking and cringing thinking maybe that shit was goofy and autistic as fuck
