According to this thread, what you're doing does sound like it's self-harm. It doesn't have to bleed for it to be counted as self-harm, and even if it didn't fit any of the technical definitions, the fact that you're doing this and that it seems to be bothering you means that it's worth addressing.

As Dez said, it's easy for behaviour like this to escalate, which is one of the things that makes self-harm so dangerous and difficult to deal with. Soon enough lines can get blurred and what felt like "enough" before may not give you the same relief it once did, and you might find yourself doing more damage as a result. That's why it's so important to start dealing with it as soon as possible, so that you don't give it a chance to get worse and you can find other, safer outlets for your emotions.

I would encourage you to ask your counsellor about their confidentiality policy as that's the best way to get an idea about whether they would have to tell anyone if you opened up about the self-harm. For example when I started seeing my last counsellor I asked her about confidentiality, and she explained that unless I posed a serious risk to myself or somebody else she wouldn't be obligated to tell my parents. It was a little nerve-wracking asking her so directly, but it did mean that I was then able to understand what her policy was and how much I could tell her without her having to break confidentiality.

Remember that the more honest and open you are with your counsellor, the more support and advice you'll receive in return. It can be scary to talk about things like self-harm, but in the end it will be worth it because it will mean that your counsellor (whose job it is to help you) will be able to work with you to come up with ways to deal with both the self-harm itself and the issues behind it.
