rerun119 speaking for myself here, because I like what I like. There are vast amounts of food, games, books, songs, movies, women, ect. Having favorites and wanting more of what's preferred, is tied to everything. But in porn, I prefer who I am genuinely attracted to and not just someone who's "hot". To have an endless amount of who I like, is that not a beautiful dream. Besides, with all the copy & paste sex position and situations happening in most videos, I feel there is more to be had with each actress. My vote for them doesn't say, but I am also voting for something new to be done with their potential next scene.
And I am always open to viewing outside my preferences, it is how I find new preferences, so I get your wanting of someone new.
