No shit, it's stated in game that he and Ryan were once lovers.
The game came out waaay before sjw shit in vidya gaems though. Even if it didn't, his sexuality isn't his character. There's a lot more going on behind him than just "hurr durr im a faget". He's an insane and eccentric perfectionist, not entirely unlike Salvador Dali, the main inspiration behind the character.
Cohen is beyond creepy
I felt guilty the first time I played and killed him. He let out a tortured moun that haunted me. + I later learned that if you don't kill him in fort frolic you see him later in olympus heights
I really love Sander Cohen...he's like the Joker...except even more entertaining with more depth
