Ishtar had many lovers...

Ishtar had many lovers however, as Guirand notes,
"Woe to him whom Ishtar had honoured! The fickle goddess treated her passing lovers cruelly, and the unhappy wretches usually paid dearly for the favours heaped on them. Animals, enslaved by love, lost their native vigour: they fell into traps laid by men or were domesticated by them. 'Thou has loved the lion, mighty in strength', says the hero Gilgamesh to Ishtar, 'and thou hast dug for him seven and seven pits! Thou hast loved the steed, proud in battle, and destined him for the halter, the goad and the whip.'
Even for the gods Ishtar's love was fatal. In her youth the goddess had loved Tammuz, god of the harvest, and—if one is to believe Gilgamesh —this love caused the death of Tammuz.[2]
Her cult may have involved sacred prostitution,[4] though this is debatable. Guirand referred to her holy city Uruk as the "town of the sacred courtesans" and to her as the "courtesan of the gods".[2]
