last night the wind blew an empty crisp packet across my garden path. i wish to write about this in my next novel.

This was a documentary of a modern-day eunuch? I know of eunuchs in ancient times -- they were castrated for cultural, social, and/or religious reasons -- but I don't know of eunuchs in modern times. I suppose a man who's undergone castration for medical reasons (like cancer), or as a punishment for a sexual crime, could be considered a eunuch, but I don't think that is the normal word used for these people. Some men are castrated for sex-change reasons I suppose, but again, I don't think they'd call themselves eunuchs -- they'd probably call themselves women or transgendered. There may be some men into castration as a fetish ... now, THEY might call themselves eunuchs. Is that what the documentary was about? I think how they lead their life (what they say to their friends, family, and coworkers; how those people respond; etc) would depend on their reasons for being the way they are. I mean, a man who had cancer would answer those questions very differently from a man with a fetish. As for going to the bathroom, I think if they still have a penis, they surely would use it to pee out of ... why re-route the urethra, but keep the penis? And if their penis was removed, where they pee from would depend on how the reconstructive surgery was performed (the urethra would have to be re-routed to some orifice -- so that is where they'd pee from).
