It's this, of course. Male homosexuality was condemned in the Hebrew Bible. So was transgender (a man with crushed testicles or a "cut off penis" was not allowed in the Temple).
Men were allowed to have as many wives and concubines as they wished, of course.
There is no issue with what women do when they aren't having sex with their husband, as long as she doesn't fuck another guy. There is no condemnation of women fucking other women, because women are second (or third) class people, so who cares if they take pleasure with each other. All that matters is they don't get knocked up with another man's biological child.
There were however, male prostitutes (the word used is "holy ones") in the Jerusalem Temple, as well as male priests of the female goddesses in Canaan (Judah, Israel). These were called "dogs" by the Temple priests, and were finally forced out of the Temple and their sacred sex duties.
Of course, much of the late Hebrew Bible and all of the New Testament were influenced by the Graeco-Roman culture of the day, where male homosexuality was accepted. The dominant culture didn't need to focus on reproduction just to survive, whereas the struggling, basically enslaved Hebrews did.
And so... all that background filters down to our prevailing paradigm of lesbians being hot, while gay men are seen as weak and perverted.
