Ranma remembered when he first got cursed; he had wondered as to 
what it was like for a woman.  He had seen both his mother and 
sister masturbate at times - his family was never shy about such 
things.  So he copied as best he could what he saw them do and 
shakingly brought himself to relief in his cursed form.  He had been 
ashamed at the time. 

Yeeps.

       Haven't you read "Chinese Dreams" by James Stone?

Which one is that?

Ranma didn't know what to do, so he just copied what he saw from his mother 
and sister (of course, Nodoka did it purposefully while Ranko is just 
uninhibited) and what felt good at the time.

He was ashamed because of the stigma commonly attached to masturbating and the 
fact that he had done it as a girl.  Ranko had done the same thing in her 
cursed form, but it neither had a place in the story nor is she ashamed of it.
