Mostly I look for distinct features that turn me on, when I am in the mood to go exploring. Also I like to look up content from certain persons I already know by name and find attractive, because of their feature(s). The act is the least important point from this list, but I'll tend to skip parts of a image album or even leave videos as a whole aside when persons with distinct features or attractiveness I otherwise prefer are doing things in them I do not like.
