Sex in porn isn't really romantic or nice to look at. I've looked at porn too on occasion myself, and it looks basic stuff to me. Sex is different when you and your partner have feelings for each other and there is sexual attraction. I've been sexually active for years, but I stick with partners I actually enjoy being with, loved and there is an attraction. Porn doesn't do anything for me either. If you aren't interested in porn, you're not interested. It's no reflection on how it is going to be when you, yourself, want to be intimate with someone you know, rust and feel safe about it.
It sounds like watching things like this is effecting you so it's best not to look at any of it. If a friend asks to to look at something just tell then no, you're not interested.
