I’d say Sansa is still a virgin. She was forced to marry what’shisname by Littlefinger.
Sansa was raped by Ramsay Bolton
"whatshisname" is Ramsey Bolton; and, he basically raped her on their wedding night. The scene was a difficult one to watch. Theon Greyjoy was forced to watch by Ramsey.
I don't believe that Lady Sansa will ever marry again after that experience with Ramsey.
