For me it's a bit of both..i enjoy it, yet at the same time, it's torturous and can be unbearable, depending on the technique used and where..it's why i love bondage combined with the tickling.. i simply must endure it whether i wish to or not..
if they enjoy it i think thell let ya and in a good way even ask for it ^^ if they hate it u probably get a lot of swearing and probably the shoes u may have removed thrown at ure head
