Sticking to tickling videos only, I am saying women participate in ticking videos for the money.
Next I'm saying watching tickling videos is a lesser substitute for participating in tickling videos.
Finally I'm concluding, since money results in women participating in tickling videos, money is what will result in women watching videos.

I have no idea what content women want in tickling videos much less what content they would be willing to pay for so I came up with the answer you need to pay them to watch. Partly being a smart ass but also considering there is not a good answer.
