I dunno man. I was watching the 2 Berserk OVAs and Soredemo Machi wa Mawatteiru, neither are particularly big on fan-service (though there are sex scenes in Berserk it's more for dramatic effect).
She should read more manga. Some particular ones like Yandere Kanojo or Angel Densetsu
Maybe watch this season of Genshiken. It targets mainly female otakus and therefor males as well because they want to see otaku girls doing otaku things.
Tell her to stay away from Rom Coms with a Harem and Ecchi element and she'll be in business. Those types will generally be geared towards the male population.
Magicka Madoka and Black rock Shooter are focused on female characters and don't really emphasis fanservice. While they have some violence, i don't think they are "gorey"
