I'm trying to figure out how anyone can be a celibate homosexual while also living together with someone of the same sex. Do they just not find each other attractive? Otherwise it sounds like a recipe for disaster.
You assume gay people want to have sex with every other gay person of the same sex? It doesn't work that way. Do you think that someone like me who is gay wants to have sex with all my other gay friends? Again, it doesn't work that way. There are a lot of factors that determine attractiveness to another individual.
