Was sex violence present in Greek myth’s before Ovid’s work?

So this question has been eating me alive for awhile.

While I was doing research about Medusa’s myth I learned that on the Greek versions there was no mention of a rape; it was either consensual or left unknown. However, it was on Ovid’s Metamorphoses that the tale of Poseidon raping her appeared for the first time. From there I did further research to learn about Ovid’s Metamorphoses; understanding that his work was influenced by his exile and his anti-authoritarian views, and he used the Greek gods as characters to portray his critique.

And that left me questioning, was sex violence/rape actually present in Greek myths or was this theme added to the myths after Ovid’s Metamorphoses was released (and due to its success which spread far and wide)? I’m very curious to know since I do not want to spread misinformation regarding actual Greek mythology.
