It s not totally clear what the source for this material is but the list of male lovers seems to be coming from Plutarch s Erotikosso a good many of these relationships are late literary invetions and not widely attested I m inclined to get rid of most of them but not allHylas is Herakles eromenos in Apollonios Argonautica if I remember rightbut I m guessing that Admetus Jason and Nestor are rarely if ever said to be Herakles lovers
