One way of learning about your orientation is to compare your reaction to supposedly-sexy scenes to other people's reactions.
I was thinking about the movie "Who Framed Roger Rabbit" recently, and thought back to Jessica Rabbit's introductory scene. I remember seeing the scene and realizing that it was supposed to arouse the audience. I felt upset with the moviemakers for so blatantly trying use sexual arousal to try to get more sales. I didn't feel any sexual urges from that scene, though that may have been because I was only 11.
I have always had a pretty similar reaction to any such scenes, in that I just turn away, close my eyes, or go and make a cup of tea. I've always done largely the same, and do so even know, because I just feel entirely uncomfortable with such scenes. And, nowadays especially, the like to just stick them in anything even if there is not even the slightest ounce of context.
they don't bother me, just indifferent to them.
