Baseball99 is correct about the pharmacology of caffeine.
Belonging to a family of compounds known collectively as methylxanthines, other members of the class include theophylline, theobromine (the "feel good" agent" in chocolate) and other derivatives which have mild to moderate diuresis potential (make you pee) and are known gastrointestinal and cardiovascular irritants. Its other properties include the classic effect everyone looks for as a central nervous system stimulant and adjunct analgesia (pain killer) when used with aspirin, acetaminophen (Tylenol) and multiple-drug combination products. It is used in multiple therapeutic applications precisely for its interesting pharmacology.
Caffeine, contrary to the old wive's tale, does not stunt growth. It is used in the neonatal intensive care environment to treat certain types of breathing difficulties in premature infants. It would never be used for this purpose if it did stunt growth, because it would be contrary to the entire purpose of the neonatal ICU--to get the kids to mature physically so they can be stabilized and sent home with their parents.
It is more likely that a temperature difference caused your dick to shrivel than the caffeine. Even minute variations in temperature can cause this.
