DearS: Ren has subtext with Neneko who also gropes Ren as soon as she meets her, Ren has subtext plus a opening-credits kiss with Miu, and then Mitsuka-sensei says to her at one point "I don't care if you're a girl, that body was made for love!" Also, Ren gets several fangirls at school who constantly urge her to leave Takeya and hang out with them instead.
In the manga. Mildly hinted at with Khi and Takeya (Khi doesn't mind being 'ordered' by Takeya...). Played straight with (to the displeasure of) Hirofuni and Xaki. Khi's relationship with 'Young Master' also had some shades of this too.
