I'm happy to expand.
Fetishes and/or paraphilias are very much like the branches of a tree. The closer you get to the leaves the more specific the fetish. But as you work your way back down toward the ground, twigs merge into branches and so on. Thus a wide array of specific fetish behaviors all share a greater fetish classes traits and so on. When you reach the trunk you are at "Human Sexuality" everything.
Response Control is a major 'branch' of the Dominate 'branch'. Note that because Domination can be done in many ways (Direct control, Psych Ops, Voyeurism) flavors of these fetish areas filter down to the Response control branch.
Response Control (RC for simplicity from here out) is best defined as Arousal by causing.
This is a wide area.
If you tickle someone you cause laughter/stuggle/begging/panic/arousal.
If you bind someone you cause stuggle/panic/arousal/(more depending on bondage type)
As a voyeur you are causing embarrassment, or the potential thereof if the act was know.
If you watch some one masturbate you are entering the feedback loop of the person acting in a highly personal way, seeing a vulnerable moment that is usually private. That's a form of Psychological control.
Forced orgasm/denial of same is obvious.
Bloodplay, Breathplay, humiliation games all fall into the area.
Giving a massage or causing a partner to orgasm are fair game. One enjoys seeing what touching 'here' will do. Or what this position will cause. RC lovers are often more apt to not orgasm by choice during sex, to prolong the effect they are causing on thier partner. Only finishing when satisfied with the result they worked on the person.
And so on...
Some will get off on seeing a person wrestled into submission and bound. Start to finish. The seeing of control imposed is the aspect keyed to here.They are seeing a subject being forced into limited response sets. Same idea as why bondage is arousing to the RC person. It allows the exploration of responses that are harder to see in normal times.
Playing/watching Strip poker would pass. The loosers are being 'controled' by the winner. Seeing them stripped keys the vulnerbilites of public nudity, and they resact.
Tickling is an interesting fetish because it's a bridge fetish that ties a lot of areas together. Control, Domination, Humiliation, Involuntary physical response, physical response exploration (If I touch here...) As it Co-ops bondage for effective play, that side of control gets pulled in. As it focuses on body parts (feet) specific groupings of folks who like them are tied in. It's a very flexible fetish for connecting to others.
Also, as tickling is part of the normal human emotional/physical growth experience it's cross cultural and encountered by just about all people as they age from infant to child to adult.
Exposure is a factor in fetish acquisition.
For many RC folks tickling is the first RC stratagy they could employ thus they come to like it. Some never move past, others do, but find it a special subset they return to often.
OK that's a rough sketch. Ask specifics for better answers. I'm happy to do my best for any who ask.
And a bonus: If you like to see people get themselves off:

And it's sister sites are a great place to visit. The month membership is well worth the price. They have several hundred clips.
To Mistress Aura, as to why you get so mad when people whom knew about your fetishes tried to discuss or share them, it could be simply a matter of control. You are aroused by seeing this stuff in a way that YOU cannot control. It's a very intense and involentary thing for you, and it's a tool that a knowledgable Dom could use to get a strong grip on you. You don't like the idea of being controled period. That these people make you feel vulnerable by poking the topic activates your defenses to Alpha level.
