Ok I know this will sounds like a joke but I'm looking for a serious answer here.

I want to ask the following; Is drinking human breast milk straight from a woman's nipple dangerous and harmful to an Adult? I searched the internet on this topic, but all the information I found was regarding the purchase of "human milk bags" online, talking about the dangers of consuming this for adults, and how you could get Hepatitis or AIDS when drinking that milk that they sell online, among other infections or diseases, and there were articles explaining how those infections were the product of the poor preservation of this type of milk, such as the fact it is unpasteurized, whatever that means. But in general the information implied that the risks of consuming this milk were due to not knowing the origin of that milk, and what procedures it had to preserve.

However, I didn't find any scientific source for answer my real question, It is dangerous for an Adult to drink breast milk, direct from a lactating woman?

The reason I ask this is well..., I'm writing a romantic story, and I want it to be scientifically accurate. Don't judge me ok, I think this is an important question that we should all ask ourselves.
