soothing / calming effect

[Gino]

I'm not one to get my feathers ruffled but seeing a news clip recently made me get angry. I found myself absentmindedly massaging my boobs and just then I noticed I was relaxing at the same time my anger was subsiding. 

The calming effect of massaging my boobs was a revelation to me, and now I'll massage them to sorta zone out / relax before going to sleep. 

Is this common or am I uncommonly lucky?

When I am overly focused on something I find I like to feel a boob as I concentrate.

I find that at times at my desk I to will take my hand and place it gently over the breast and let my fingertips rub along the underwire.  Calming, I guess it is.  I just won't, and don't do it in public or anywhere else.  Only at my desk.  Perhaps that's why.

It’s very common. The nerves in breasts have been documented to not just be sensitive for dopamine pleasure nerve endings. But also correlated to releasing oxytocin when massaged or kneaded. 
As with anything in the body, different emotions heighten the effect of things. In this case, stress, oxytocin releases and provides a calming effect. 

I noticed it a couple years ago when anxious I’d find myself cupping one and eventually realizing how it’s become a particular action to calm self when not in presence of others.
