When medicine says for external use only, does this exclude under the foreskin?

Question

Because, strictly speaking, under the foreskin is not internal. Foreskin is just a layer of skin folded over the penis head.

Answer 1

your inner foreskin and skin on your penis head is a mucosa type skin like under your eyelid or in your mouth so whatever you put on it can absorb quickly and burn just like when you get soap in your eye.

Answer 2

Usually that warning is that it is ok for any area, EXCEPT the genital area, mouth, ears, eyes or nose.

Answer 3

it means dont eat it
