It is a story about an average 24 year old guy who has trouble with women and getting laid. He wishes to become a girl, as he believes that his life would generally be easier and all of his troubles would go away. A goddess grants his wish and he becomes a girl that both guys and girls want to have sex with. Standard stuff.
The story isn't too deep...it is a good and intriguing gender bender plot.
The art is pretty well done and is visually appealing. There is lots of sex scenes, all of them are well done...so if you do not like reading
material of this kind, I would avoid Nyotai-ka. Otherwise, I recommend this manga. Overall, Nyotai-ka is a decent gender bender that includes a captivating story and a somewhat interesting cast of characters.
