I don't blame the show too much for this in that Cogman said they wanted to film more scenes of Loras mourning Renly (and clearly expaining that he's just drowning his sorrows with that male prostitute) but they were cut for time.

...in all fairness Loras doesn't do much in the third novel, so I didn't expect him to have much to do in seasons 3 and 4. But then Loras gets a major new subplot in the fourth novel...but it was cut from Season 5.

HOWEVER, other subplots related to that one will appear in Season 6, so there is some chance they'll stop backburnering Loras's subplots.

You see the problem is more than when he doesn't have an actual subplot for a whole season (not their fault) they'll make a wry remark here or there about him being gay....I don't think they realized....that this kind of "added up" over time; that if it's really the only screentime the character gets, eventually that becomes how they are presented.
