japanese weman

i read alot of doujin and one of my favourite tags is houswives
i am thinking of going to japan soon and i have done alot of research and came across a couple of articles saying japanese weman do not get enough sex and its not just one or two alot of them say this becuase of work hours or schooling.

so i was wondering do what the doujin say depict the truth? please answer

Not everything you read is truth and doujins just exploit some fantasy involving housewives.

That, basically, each manga you read are personal fetish's....IF you come across any of them, consider yourself lucky :P (That's if you like the fetish)
