Or HaChaim on Genesis 34:2/אור החיים על בראשית ל״ד:ב׳

1 נשיא הארץ, the prince of the land, etc. Shechem's position in the community was the reason that no one came to Dinah's assistance when she cried for help against being raped.

2וישכב אותה ויעניה. He slept with her by forcing her. We must understand the sequence of how the Torah reports what happened [not "he forced her and slept with her," Ed.] in light of a statement in Horiyot 10 where the encounter between Yael and Siserah is described. The Talmud says that when the wicked derive physical pleasure this is a source of pain for the righteous. The Torah therefore tells us that although Shechem slept with Dinah in a perfectly natural way, not subjecting her to painful perversions, Dinah felt tortured instead of enjoying the experience. Her distaste of Shechem is obvious; this is why Shechem had to expend so much effort by "speaking to her heart."
