This is an interesting question as I think part of it is determined by one's perceptions and preferences. If you struggle with it, meaning causes distress in some way (i.e., object dependent) then it could be a paraphilia..but if you can be satisfied without also...fetish.
I guess my answer would be no. I very much enjoy anal play, and my wife enjoys playing with my butt every chance I she gets. DO I like it..YES!! , would I want it most if not every time..YES, is it necessary for arousal..no.
A question I think would be also interesting to ask would be that of sexual deal breakers in a relationship...I would not be able to be with a woman long term unless they liked anal play and were adventurous. Does that mean it's something I am dependent on? Probably not, more so I want to be happy and I know what I really like...but still..perception I suppose.
