How can you stand to watch Sailor Moon, which has younger characters and is even more sexualized?
I wouldn't say Sailor Moon is sexualized at all really.
The two main couples in the show Usagi/Mamoru and Haruka/Michiru never go into anything all that deep and the same goes for the Transformations.
Hell they even handle Usagi have a child and we never see so much as her with out her top off in a sexualized manner.
