mine are kinda cold after pumping, I have bad circulation.
I find if I massage over top of a t-shirt, I get more friction and that heats em up nice and quick!! That's my fave way to massage. Or you could try a heating pad before or after.
I do think it's better for them to be warm tho, I associate coldness with constricted blood vessels, I think heat opens them up more
