Real estrogen with me instantly causes nipples to go on hyper alert
Whereas pm causes whole breast too activate but I do swap about
My nipples are constantly "on alert".
Either I am being sucked out hard by my electric breast pumps (as of now, thank god for Johnson's baby oil!), or I am going out wearing supple nips under my bra, or I am so sore from pumping that I am wearing soft nipple shields in my bra cups to prevent myself being chafed and pushed back in.
