I wrote a long post about this, but I'll cut to the chase:

Estrogen unstopped the font from which my feelings poured fourth. Feeling myself change while feeling myself change was strange.

Progesterone, on the other hand, made me crazily horny and believing against reason that I could and must get pregnant. But that's not the craziest thing. I woke up every morning with slightly larger breasts, and my nipples were puffy, more sensitive, the skin texture changed, and they were aching. But that's not the crazy thing either-- there were other spots on my body feeling the same way too.

...

To catalogue, I have:

• A patch of hair ~4 inches under my left nipple

• A patch of hair ~6 inches under my right nipple with a tiny 'mole'

• A 'mole' two inches under my right nipple

• A 'mole' on the smooth part of my right armpit

I didn't think about the sensitive spots on my skin, I chalked them up to a recurring zit.

But these 'moles' remained there (and they've always been there). And their textures changed back just like my nipples did.

Turns out humans also have what's called a "mammary ridge" or "milk line" on which we can grow what are called "supernumary nipples".

And I, Nipples Georg, seem to have at least four extra nipples!

These could just be moles or some other skin thing, but right now, my bet is just that I have way too many nipples. I don't know why my biology is so weird. I can touch my brain with my tongue and move my eyes independently and rotate them, so I guess this isn't too much extra.

TLDR: Went on estrogen and progesterone, noticed I had extra nipples, play Outer Wilds.
