I think the common belief is that if you don't want your gf to know, it's cheating. But does this apply to situations where there really isn't any sexual, emotional, or flirting?

Here is the situation

I really like ear massages and ear picking. My previous girlfriend would do this for me, but my current girlfriend won't (I've asked multiple times). Because this is hard to find someone to do commercially (in the US, they are common in Asian countries), I have hired someone on craigslist to do this for me for a fee. I've gone a few times already, and it's literally just a ~30 min ear massage and ear picking session. That is it. We don't flirt, or touch in any inappropriate way. I do this maybe one a month or so (for the past few months).

I obviously haven't told her and don't want to tell her. It's not that I feel I am physically or emotionally cheating in any way, it's just that I know she would probably take it the wrong way.

In r/relationships opinion, SHOULD this be considered infidelity? Am I in the wrong for not feeling bad about this?
