Very odd syndrome...please give me advice on what to do (serious answers only)?

Hello, well my name is James Mcphearson. I am 17 years old, and have this very odd routine I do whenever I see either a park bench, a black barbershop, a Cosco superstore, or Jennifer Lopaz (The list grows every day, I don't know the relevance of any of them?). Whenever my eyes catch one of these, I immiediately drop what I am holding, stop any conversations I am having, or cease any actions, and drop down on the ground and start doing the worm. I then squeeze out of my trousers, flip on the other side, and grasp my crotch. This has been happening for almost a month now, and there is no way I can control it. Please advise.
