It really annoys me that people casually attach the term "masturbatory" to things to criticize them as... selfish?
I dont care that when people do this they arent actually trying to comment on sexuality, it indirectly shames the most harmless and abundant form of sexuality.
Also as a theater person sometimes I hear "No one wants to watch people masturbate on stage" and I just think in my head "That is LITERALLY an untrue statement".
