The pery old anmie man is very difficult to write. The line between comic relief and plain glorified sexual assault is extremly thin. I am glad that you may change Jiro's Restaurant Scenes later.
Maybe less touching and more teasing remarks?
It should also be part with Jiro actuall needs and personality. Does he want to get touched, cuddled, loved and admired by others (despite his age) ? That is easier and morally save when the other option: He likes to grab others and assume control in Sex, showing of his Strengh/Endurance and that the old men still got it.
