Maybe this online summary of Ramsay's wedding night will help you make up your mind:
Ramsay's Wedding Night Is Somehow Much Worse
Rather than being handed over to Ramsay Bolton like a sack of old Pogs, at the end of A Dance With Dragons, the fifth book in the series, Sansa is still safely in The Vale posing as Littlefinger's daughter (we are admittedly stretching the definition of the word "safely" in this context). Instead it is Sansa's gal pal from the Winterfell days, Jeyne Poole (being masqueraded as Arya), who is handed over to the Bastard of Bolton, even though both Ramsay and Roose know damn well she isn't really Arya.
Ramsay marries Jeyne to solidify a claim to Winterfell and forces Theon/Reek to confirm in front of the rest of the Stark bannermen that Jeyne is actually Arya (even though Theon also knows damn well she isn't).
Now, on the show, viewers got mighty pissed over Sansa and Ramsay's "wedding night" and how it was yet another example of how tasteless and exploitative the show has become in its constant portrayal of sexual assault. This is a 100 percent accurate interpretation, but it is our duty to inform those of you who haven't read the books that Ramsay's wedding night was mind-blowingly worse in George "Mixmaster" Martin's original text:
"No." Lord Ramsay poured himself a cup of wine. "Laces take too long. Cut it off her." [...] Finally the gown fell away, a pale tangle round her feet. "Her small-clothes too," Ramsay commanded. Reek obeyed. [...] Ramsay rose, the firelight shining on his face. "Reek, get over here. Get her ready for me." For a moment he did not understand. "I ... do you mean ... m'lord, I have no ... I ..." "With your mouth," Lord Ramsay said. "And be quick about it. If she's not wet by the time I'm done disrobing, I will cut off that tongue of yours and nail it to the wall." Somewhere in the godswood, a raven screamed. The dagger was still in his hand. He sheathed it. Reek, my name is Reek, it rhymes with weak. Reek bent to his task.
Yep. Ramsay, proving he will be difficult to unseat in the upcoming "Most Horrible Person In The Universe" awards, forces Theon to assault Jeyne. Later, when Theon finally decides to try to break her out of Winterfell, we find out that things have only gotten worse for Jeyne, as she stammeringly refuses to go with him:
"No. This is some trick. It's him, it's my ... my lord, my sweet lord, he sent you, this is just some test to make sure that I love him. I do, I do, I love him more than anything." A tear ran down her cheek. "Tell him, you tell him, I'll do what he wants ... or whatever he wants ... with him ... or ... or with the dog or ... please ... he doesn't need to cut my feet off, I won't try to run away, not ever, I'll give him sons, I swear it, I swear it ..."
So, um, yeah. Ramsay makes her have sex with his dogs.
