help

I'm trying to find this one manga where a girl likes this guy but plot twist: she has a penis. she's in high school and her friends (who also have penises) teach her how to live with having one and how to make it unnoticeable when she wears bathing suits. she confesses to the guy she likes and she found out that she has a bigger one than him. if you guys can find it that it would mean a lot to me (≧∀≦)
