ELI5: Why in most Japanese adult movies women almost cry when they have sex?
gpt
I believe that the impression such scenes (those that aren't violent) are intended to convey is this: 

the ideal Japanese woman is shy, delicate and graceful. And now this *manly man* (which the viewer is supposed to identify with) has made her *completely lose her composure*, which makes her cry with embarassment while at the same time she totally enjoys it!
