Cold tingly sensation in prostate

I've started to notice a new sensation on my prostate journey. It's a cold, kind of tingly sensation that is best likened to the almost numbing feeling that you get if you get something mint-flavoured on a sensitive area.

I first noticed this while doing some investigations into squirting. Following some online techniques I would rub the head of my penis, and after a while this would create this sensation in my prostate area. I found that after this session, the sensation could also reappear in the following days, but a different feeling to the usual butt buzz from prostate stimulation. As I've been having more success in both aneros and aless sessions I've noticed this sensation occasionally during those too.

Is this a common reaction to have from certain prostate stimulation? I wouldn't call it pleasurable exactly, and it can actually be a little distracting when it happens due to how overwhelming the feeling can be.
