Hey look! your shrimpdick is actually a medical condition!
“Micropenis is a medical term that describes an unusually small penis. A common criterion is a dorsal (measured on top) erect penile length of at least 2.5 standard deviations smaller than the mean penis size.[1] The condition is usually recognized shortly after birth. The term is most often used medically when the rest of the penis, scrotum, and perineum is without ambiguity such as hypospadias.”
