I am sure many of you have noticed the huge amount of websites out there trying to give a little flavor to everyone, some fisting pics, some anal, some celebs, a bit of this and a bit of that. One reason these sites exist and make money is because they do offer a bit of something for everyone, but the reason they lack staying power is they offer nothing to set them aside from the thousands of other sites out there. Few websites choose to become the definitive site on a subject. Those that do and succeed tend to attract a larger core following than the sites which offer only a tease of what the viewer really wants. Almost any adult topic can be given more attention then simply pictures.
Lets take fisting for example.
While many sites have a fisting section, few are devoted entirely to the fetish even though it is a popular one.
