Satyr or satyriasis.
Satyrs were male woodland deities with the ears and legs of a goat, who worshipped Dionysus (Bacchus) god of wine, often in a state of sexual excitement. A satyr today is nothing more than a lecher. A man who has an excessive and uncontrollable sexual drive suffers from satyriasis.. See nymph/nymphomania/nympholepsy.
