IMO, the best thing you can do is try to find somebody who has the same interests as you. When I say that, I don't mean tickling (though I do mean particular aspects of tickling). What I mainly mean is, somebody who matches you for your interests in a RPing session. Do you post the same length of responses, do you both like to have a theme to the role play, do you just like to get into the tickling or do you like to build it like a story, do you both like sexual aspects in tickling, do you like feet, etc. Find somebody where you both tick each others boxes, and you'll likely have a lot of fun for a lot longer. Also, keep reaching out. It can take a long time before you find the right partners. The most important thing is that you keep each others interests, because if you can't then it becomes a choir for somebody and the role play will likely fall apart eventually.
