hmmm I like to think Gojo fell first and while unaware that is the reason he allowed Geto to be close and that is when Geto fell "first" because I can't see a way to brute force your way into Gojo's life without him allowing it. Another is that Geto talks a lot during sex until he just starts babbling nonsense and Gojo turns quiet and focused (apart from initial dirty talk and teasing) he becomes really quiet nearing climax. I can't remember anything else rn because I never type ideas down ☠️
