I know the title sounds bad but let me explain. Fake names for obvious reasons. I (28m) was over the apartment of my sister Becky (35f) and her roommate Cassie (37f). Becky and Cassie were watching a video featuring them and another woman Jamie (30-something). They were all really drunk and making a fool of themselves. To me, Jamie looked so beautiful. Despite the fact she was super sweaty, messy, and part of the video feature her puking with my sister and roommate laughing at her, I couldn't take my eyes off of her. I started hanging out with my sister more. Then about 2 weeks after seeing the video, I got to meet Jamie. I asked her out and she said yes. A few days later, my sister asked me if I realized that Jamie was the woman who was in the video with her and Cassie. I said yes. Becky asked how could I be attracted to Jamie after seeing that video. I told Becky that I didn't mind. Becky said I am a weirdo and a jerk. She said I have no taste in women. Am I the asshole ?
