There hasn’t been an increase in same sex relationships since the 1920’s, when it was first being studied.
The increase has been purely sexual.
>that’s still gay
When people say “relationship,” it’s implied that they mean a romantic relationship; dating, monogamy or something close to if, marriage, commitment… They don’t mean “fuck buddies.” If there’s a girl you get together with every Tuesday and Saturday, and the entirety of the situation is you going to her house and immediately going to the bedroom so she can suck your dick and you can fuck, and a friend asks you about it, would you say “we’re in a relationship?” No, you’d say she’s a fwb or something similar.
That type of gay “relationship” has skyrocketed because of ubiquitous internet porn.
