Question: do tyrion and sansa ever consummate?
Answer: It's murky, but the answer is most likely no. Let's look at the facts: Sansa and Tyrion's marriage was famously never consummated. ... "What if I never want you to?" Sansa says — and she never does. In fact, their marriage never being consummated is why Littlefinger is able to bring Sansa to Ramsay in the first place.
