Gura would probably be more surprised/bothered if people told her they DIDN'T.
I sincerely believe Ame lurks these threads partly because people (men) are vocal about masturbating to / cumming on pictures of their oshi, and may enjoy reading people gayposting at each other.
As for the last question... Sora? Would she be bothered by it? I don't think she goes into that direction even after becoming an adult.
