>Is every single female fan a fujoshi?It's hard to tell due to a lack of studies, but I noticed that Goh attracted a lot of fujoshi (women who like "boy love") and fudanshi (male equivalent of fujos) due to his interactions with Ash.
>Do female fans even like heterosexual ships or try to do their self insert to fall in love with the male main character?Yes to both. Many of them like straight ships too, and a sizeable bunch of them like to self insert as one of the male characters while consuming yaoi.
