Generally I find that porn gets boring pretty quick. Usually I prefer to read a story when the mood is on me. However if someone has some good suggestions, I am always willing to learn.
I don't have any 'go to' vids.
I usually just search for whatever I'm in the mood for at the time.
Watching the same things over and over would get very old for me.
I also find the vast majority of porn to be boring, and I've never quite understood men's fascination with it, particularly the pathetic excuses for women faking orgasms that most porn displays. While I am not a lesbian- I have only a very small history of sexual encounters with women- nonetheless, I do find some lesbian porn to be beguiling. The best example I have seen of this is the film, "Blue is the Warmest Color".
Some days going straight for a S&M porn video is just what I need. Other days, I enjoy relaxing and enjoying my own sensuality. I dismiss the idea of having an orgasm and make play about enjoying the touching rather than attacking my clit or gspot. This helps me to relax mentally. I don't feel pressure to reach a goal.
People usually make fun of softcore porn, but I like Seven Lives Xposed and Sexy Urban Legends. If I have trouble finding something I like to get me off, I go to a scene from one of those fictional reality TV show pornos to climax quickly. I think it's the trashiness of reality tv shows combined with porn, that I am fond of.
Public bathrooms are dirty and get grossed out by them IRL, but for some reason I love watching public bathroom scenes in porn, such as another go-to of mine, hardcore. Oksana D'Harcourt having sex with a stranger in a public bathroom of a restaurant, while her boyfriend waits for her, it's been my go-to for years: http://www.tube8.com/hardcore/french-oksana-fucks-stranger-in-the-restroom/385741/
