Not to argue the point, but this sounds strange to me. If crossdressing, completely transforming or wearing only "favored" items, causes arousal on a recurring basis, I would call this transvestic fetishism. Lots of guys do this and have good control of it. But the APA won't call it this unless it "causes significant problems".
It sounds more logical to call it what it is, but don't consider it a disorder unless it "causes significant problrms". But I guess I'm not seeing it from the APA point of view. I guess if it's not a problem it doesn't exist.
To me, it's like stealing money is not stealing unless it's for a certain amount, or it's not eating if it doesn't cause me to gain weight.
