Okay okay okay.

This is an extremely specific kink complaint to have but

if you are writing erotica that involves lactation, human breastmilk is pretty much universally described as very sweet, creamy, and comparable to almond milk. It's not watery or bitter unless there is something very seriously wrong with the lactating person's health.

This is not hard to find information. Breastfeeding parents often try their own milk at least once, partners of breastfeeding people may drink from their partners, and you can literally buy breastmilk online to drink. We know what breastmilk tastes like. Please give humans more credit in your erotica.
