I ask the question as a writer who wants to give story readers on this forum what they want and for the benefit of myself and other writers who may gain something from the responses that the question brings. For example, from the results so far, we can see that we would please most people by featuring characters in the 25 to 30 age range and that if we involve characters who are 55+ then we are entering a more niche area.
Many people on this forum have specific tastes and only visit particular sections, therefore I don't believe it would benefit the writers by asking the question elsewhere as it's the story readers on this forum from whom it is most important to get responses.
Age difference is part of a domination aspect of tickling to me, with that said i always enjoy MILF aged women 30-50 tickling/domming young women in their 20s
