You know what I've always wondered?

[Clueless Morgan]

Apparently as a species we have been selecting for bigger breasts and penis size for a long time.  We're pretty much freakasaurs of the animal kingdom for our size.  You women not only have breasts ahead of needing them, you're also receptive for mating whether any eggs are ready to go or not.  We're weird.

If you're interested in the subject you could read Jared Diamond's book The Third Chimpanzee which talks about genital sizes among the great apes and why humans probably developed such strange genitals.  For example, your average male human has very conspicuous genitals compared with the average male gorilla, whose genitals are small enough to not even really be that visible.  Why the disparity?

Read the book, it's really interesting.

But there are several more examples of polyjuice potion being used in the books where nothing goes wrong - Harry and Ron into Crabbe and Goyle; Barty Crouch into Mad-Eye Moody for a whole year; Crabbe and Goyle as random students in Half-Blood Prince; the seven transformations of the Order members into Harry; Ron, Hermione and Harry into Ministry employees to find Umbridge and the locket... you're focusing on the one time in the books where it went wrong and forgetting that that's far outweighed by all the times it went right.

And the point of the animagus transformation is to turn into a non-human animal anyway.

Why are humans so special?
They're just animals... the same as the others... and if you're magically retaining all the cognitive function of your original self, there's no need to alter your brain mechanisms. So it's just the same!
Also the polyjuice potion went wrong one time in the books.... how many times did an animagus screw up their transformation?

The animagus transformation isn't an easy spell, it's complex, difficult, and at some point involves holding a mandrake leaf in your mouth for a month.

It's comparatively much easier to brew a complex potion than to learn to become an animagus, hence why so few wizards and witches choose to learn to do it and why it was extra impressive that James, Sirius and Peter learned to do it while still in school.

But I don't know, necessarily, that you can control what kind of animal you would turn into.  The best guess at this point is that it might be based on some aspect of your personality.  There may be limitations on the spell that we just don't know about because they never come up in the books.

I don't know that either, but one must assume anything goes. We're talking magic, after all! Not just some physics pre-determined machine.

Yes, we're talking magic, but I'm talking about the real magic in Harry Potter that has rules and theory behind it, not just the willy nilly shit made up in bad fanfiction.

Aye... I've heard the same... from someone who claimed to have some 2kg on each. And she also considered having a reduction.... and yes, whatevs, the nipple repositioning is a thing. Which means no ability to breastfeed, ever, because all the connections are severed.... as well as all the nerves.
It must suck to loose all sensation on there.  

Yes, whatevs, the nipple thing is for real.  They're removed and then reattached or kept attached and, like, sewn around to reshape the breast... if you really want to know, google it, but be prepared for some gnarly stuff.

As for sensation loss, I'm in for that whether I get reconstruction or not.  Reconstructed breasts (post mastectomy) are numb, as can be a flat chest if you don't get reconstruction. /fun fact
