Well, yeah, it's a form of OCD, but how much time of your day does the behaviour take up? What will happen, will you feel anxious if you try to stop the behaviour?

If you experience intense distress over it, you should seek help. also if you have other "rituals" that you feel you HAVE to keep doing. Sometimes it's just a phase and other times the OCD can grow and become an obstacle.

You could read some books about it or use "response prevention" - try to force yourself to not do the behaviour and the anxiety will surely drop after a while. it's unpleasant but in the long run, it works.
