Honestly, in my opinion, I think more people would step up to buy your stuff if you posted 1 or 2 sample pics and maybe a short sample video. Not trying to be that guy asking for free stuff, and come off as a bum. Just saying. If people can see how ticklish you are, they'll buy more vids. If people can see how cute your feet are, they'll order more pics.
Take a lot of the professional tickle companies for example. A lot of them release samples of current vids or their work. Again, not trying to be mean or nasty or disrespectful or cheap. Just offering you a suggestion to potentially help you out. Good luck.
