>>62227107He probably just didn't want to make any sort of statement regarding his sexuality as Vesper. You could pretty easily infer that he didn't have much interest in sex based on his comments as Vesper. He talked about how he didn't like Kakegurui, saying it was just a worse version of Kaiji but with cute girls, and that he doesn't really give a shit about cute girls.
I think his lack of interest in sex is his general disgust with other people. He's a neat-freak and he talks about needing to constantly brush his teeth, shower and wash his hands. He doesn't like 3D porn because he literally imagines the smell and he hates it.
I feel like Randon/Vesper is the worst person to be jealous of because of how unsuccessful he is sexually. At worst, any given person in this thread is pretty much even with him.
