Is it normal i watched porn with my sister?
A few weeks ago my sister bought a new flat screen tv. She asked me if I could come round hers and set it up, so being a good brother I did. When I arrived and saw the tv it was huge, I made a comment about how big the tv was and she replied with something along the lines of "can you imagine porn on a screen that big." I thought it was weird but I laughed it off, once I had set it up and mounted it on the wall I suggested testing the tv, sky and her DVD player. We checked the tv and the sky and it worked fine, and when we went to check the DVD she pulled out a porno and said "what about this" and laughed, I laughed as well assuming she was joking but she put in the disc a started it up, at first it was weird but she broke the awkward silence by noting how fake the orgasms were, we then spent as while critiquing the porno and laughing but once we had finished doing that the awkward silence was back and we continued watching the porn in dead silence, I was really turned on and got a hard on and we watched til the end of the porno after which I left, she thanked me for helping to which I replied no problem, when I got home I was still kind of horny from the porno so I went online and watched one for myself. I've only seen my sister once since then and it was really awkward, there were lots of other people so we couldn't exactly talk about what had happened. Is this a normal thing to watch porn with a sibling, or am I right to feel weird?
