I vote for "other" meaning All of the above.
I'm not sure if there is a right answer to this.
I love tickling women. And I love doing it on video.
This is how I make a living, but for me is more than just money.
Is fun, joy and pleasure.
Is my fetish.
I also love watching woman tickling woman, and I love to step back and just film it.
The same thing goes for clips that I buy.
Female/Female tickling clips are lot fun to watch, but so far, with very few exceptions, the most effective tickling clips I have seen have been man tickling woman. The same goes for the most effective clips I have shoot.
In the three years I have been doing tickling clips I have done a couple of girl/girl specials, the first one and all time favorite Addie Juniper/Emily was my first and an instant best seller which is still in the top 5 list.
Next There was a series with Emily/Violetta which didn't make too much noise, and then Violetta with Tia and then Emily tickling an unknown called Olivia and this was a flop. This proves that making a girl/girl video do not guarantee sales and is a very risky bet to make because as a producer it costs twice what a regular "me tickling girl" video would cost.
For over a year I have been looking for the right combination of girls to put together. A combination that would make a safe bet and finally they came together with Lexi Lee and Alexis Grace. And the result is another instant best-seller.
Now it sounds a lot easier than how it really is, because in all of this videos, coordinating with two girls to be in the same place at the same time has been the biggest nightmare. Also, contrary to what most people would think, not all girl want to to do girl/girl scenes by default. They like to be tickled by men the same way that man like to tickle women.
Having said all that, I have to conclude that porn is a female medium, and I believe that if dildos came with sperms, male would be obsolete!
