Other erectile tissue
Erectile tissue is also found in the nose (turbinates), ear, urethral sponge and perineal sponge. The erection of nipples is not due to erectile tissue, but rather due to the contraction of smooth muscle under the control of the autonomic nervous system.
(The search question was “are ears erectile tissue?”)
But I don’t understand the product! It doesn’t work as you would (presumably) want your viagra to work, and since we don’t all have elf ears, they clearly didn’t follow up on the product, and yet elves all use it? Huh? Why?
And wouldn’t you want it to be viagra perfume (as opposed to cologne), unless it’s only meant as a niche gay product?
larK: the elf’s ears were normal until the product was applied
So then it stayed that way? And they went and applied it to all the elves? Product I Don’t Understand.
