The reason I shoot mostly Asian content is because it is the type of content that turns me on most, and I believe it is a niche I truly understand.
When I shoot outside my niche, such as BDSM, I shoot it as instructional content for my Members, since I feel that they will also enjoy learning about variations within the niche.
I think that real true BDSM aficionados will instantly recognize that I do not know their fetish, and find my work disingenuine, since I do not share their fetish, so I do not pretend that I understand it fully.
I do think that other genres and fetishes can be learned, but they cannot be faked very well for a core fetish audience. For example, I can't imagine myself ever convincingly shooting gay content, even though I have many gay friends.
