I personally disagree with that, because I'd interpret "my pee-pee hurts" as "I have pain on urination," which is not the same as "my vulva hurts" (likely to be diaper rash or similar), which is not the same as "my vagina hurts" (so improbable that I'd be mentally running down the list of people she'd been around unsupervised).

But plenty of people conflate stomachs and abdomens, so I suspect you're in the majority.
