Clogged nipple pores?

Hi ladies, As a first-time mum, I am not sure what is normal and what is not. I am pumping only as breastfeeding was too painful for me and my baby had problems with latching. Below I am sharing photo of how my nipples constantly look. There is this white space between the pores. I am removing white parts by exfoliating with the clean towel right after shower. It comes out as white cheese like parts. It is painful when removing but not too much. I am not sure if this is the milk bleb and if it's actually normal. Even with pumping I feel a bit of a pain at the beginning of every session, but after a couple of minutes it goes away. Is this normal, and I am being too sensitive, or is this a reason for my pains? Potentially, could this be something else? Thank you
