It is not uncommon for Greek mythological figures to have both male and female lovers. That said, all of <PERSON>'s sexual relationships mentioned in the myths assembled on theoi.com seem to be with women. A few examples:
"Women of Tanagra ... often I adorned [with songs] our ancestor <PERSON> with my words, often great <PERSON> and the fifty sons of high strength whom he fathered by intercourse with the fair Nymphai (Nymphs) [i.e. daughters of the river Kephisos (Cephisus)]."
Corinna, Fragment 655 (trans. <PERSON>, Vol. Greek Lyric IV)
<PERSON> slew <PERSON> on Delos. He was said to be a Gigas (Giant) of massive proportions born of Ge (Gaea, the Earth), but <PERSON> (Pherecydes) [C6th B.C. poet] says that his parents were <PERSON> and <PERSON>. From <PERSON> he was given the power of walking across the sea. His first wife was <PERSON>, who for vying with <PERSON> in shapeliness was thrown by her into <PERSON>' realm. After that <PERSON> went to Khios (Chios) where he courted <PERSON>'s (<PERSON>'s) daughter <PERSON>. <PERSON>, however, got him drunk, and, as he slept, blinded him and tossed him out on the beach. He made his way to the bronze workshop of <PERSON> (Hephaestus), where he seized a boy [<PERSON> (<PERSON>)], set him on his shoulders, and ordered him to guide him toward the east. 351
Once there, he looked up and was completely healed by the rays of Helios (the Sun). Immediately he started back to confront <PERSON>. But <PERSON> had provided <PERSON> with a house beneath the earth, built by <PERSON>. Meanwhile, <PERSON> (the Dawn), whom <PERSON> taunted with constant passion as punishment for sleeping with <PERSON>, fell in love with <PERSON> and took him off with her to Delos. There he was killed, according to some, for challenging <PERSON> to a discus match. Others say that <PERSON> shot him as he was forcing his attention on <PERSON> (<PERSON>), a virgin who had come from the Hyperboreans.
<PERSON>, Bibliotheca 1. 25 (trans. <PERSON>)
<PERSON>, so the story runs, was the daughter of <PERSON> (<PERSON>) and the nymph <PERSON> (<PERSON>). <PERSON>, the son of <PERSON> (<PERSON>), fell in love with her, and asked her father for her hand; for her sake he rendered the island where they lived habitable--it was formerly full of wild beasts--, and he also gathered together much booty from the folk who lived there and brought it as a bridal-gift for her. <PERSON> however constantly kept putting off the time of the wedding, for he hated the idea of having such a man as his daughter's husband. Then <PERSON>, maddened by strong drink, broke in the doors of the chamber where the girl was lying asleep, and as he was offering violence to her <PERSON> attacked him and put out his eyes with a burning brand.
<PERSON>, Love Romances 20 (trans.<PERSON>)
"[The goddess <PERSON> laments her marriage to a mortal man :] ‘I will proclaim how <PERSON> loved <PERSON> [<PERSON>], and I will recall the match of <PERSON> (<PERSON>); if I go to the misty sunset, my comfort is <PERSON> herself who felt the same for Endymion upon Latmos.’"
<PERSON>, Dionysiaca 4. 192 ff (trans. <PERSON>)
This of course does not exclude the possibility that the huntsman had male lovers as well. It does however invalidate the first part of your quote. <PERSON>'s relationships with women were certainly not limited to brotherly love. 351
