Who is Zeus' only male lover?

In Greek mythology, Zeus had many lovers both female and male, but his most famous male lover is Ganymede, a beautiful Trojan prince, who is often described as his only male lover who was elevated to Olympus. According to myth, Zeus was so captivated by Ganymede's beauty that he transformed into an eagle and abducted him from Mount Ida near Troy, bringing him to Olympus to serve as cupbearer to the gods, replacing Hebe, and to be his companion. Ganymede was granted immortality and eternal youth and became the god of the aquarius constellation. The story appears in Homer, Ovid, and other classical sources. Some traditions also mention other male lovers or favorites of Zeus, such as the nymphs or young men in some regional myths, but Ganymede is by far the most canonical and widely cited as Zeus's male beloved in classical literature and art. The relationship reflects ancient Greek cultural norms around pederasty and divine favoritism, where gods taking beautiful youths to Olympus was a common motif. In later art, Ganymede's abduction became a popular subject in Renaissance painting. So while Zeus had many affairs, Ganymede is universally recognized as his principal male lover and cupbearer, often described as the only male lover who achieved divine status and lived among the Olympians permanently.
