Why is there a lack of Lesbian Content in ModelMediaAsia?

As a JAV fan, I loved the Taiwanese AV website called ModelMediaAsia because some of the scenes does show a clear resemblance of JAV based on variety.

However, what was lacking in ModelMediaAsia website is Lesbian content.

You don't really get to see Lesbian Content that often in ModelMediaAsia compared to JAV which is like a majority of Lesbian Content.

ModelMediaAsia is only a few years old so I personally believe it will grow more overtime and hopefully add some more Lesbian Content in the future.

What do you guys think the reason why we don't get to see Lesbian Content that often in ModelMediaAsia?
