Nipples Sensitive

An

I had flat / inverted nipples pre-baby. Now exclusively pumping 6 times a day they stick out all the time. It hurts when taking a shower and water hits them or when rubs against my shirts. You ladies with regular nipples, is this just what life is like with normal nipples and I’m just not use to nipples being out since mine were flat? Or is this what all breastfeeding/ pumping moms experience?
