Well, that gets complicated because in ancient Aramaic "washing feet" sometimes meant washing feet and sometimes it was a common euphemism for oral sex. There isn't really a text outside the gospels that meaningfully refers to him (and the one text that did mention him in passing is contested), none of them can be dated to less than 30 years after he died, and all of them were penned by people who were pretty uptight about such things. Is it possible there's some euphemisms in there? Maybe. Probably not, but who knows. He washed a lot of feet, but then, they literally washed their feet a lot back then too (you know, sand... it gets everywhere). Solid proof? None either way. Whether he did or not is kind of an open question that people will get very angry about regardless.

Now Paul... Paul definitely fucked, but he definitely didn't enjoy it. There's some strong evidence there that he was more interested in wrestling with the bros, but considered it his responsibility to procreate. He definitely considered enjoying it disgusting.
