said Cooper was gay and they would address it over time.

season 1--him arresting dude for indecent exposure then seeing dude at the gay bar

Chickie making a reference about him season 1 (i.e. when Ben asked her what his deal was when he first started the job and why he was the way he was and she said "I have my suspicions..." and didn't say anything else..)

his getting his drugs..at the gay bar

the garden and his "buddy" (READ, his piece)

the ex-wife situation

the tip off--the red head who was fucking all the cops NEVER went after him (the assumption that she probably knew he was gay) and cooper even said he wasn't her "type"

its been there...they're just taking their time getting to addressing it.
