Is it normal to get turned on by this?

A couple nights ago while searching for porn, I stumbled upon this amazingly hot video of a girl and a shemale, both blonde and wearing dark eyeliner. It was nice and long too (went on for half an hour) and they did all the usual (and some not so usual) stuff. Then at the end I realized that what turned me on the most was that the shemale looked and sounded a whole lot like Cher. And now I keep having strange thoughts about Cher herself. What do you think?
