You know what I've always wondered?

[pocaracas]

Does an orgasm feel the same for a man and for a woman?

Can an animagus transform himself (or herself) into a human of the opposite sex and find out the answer to the above?
Or do animagi only transform into animals of the same sex as themselves?
Can they transform into hermaphrodites? or species that change gender as they age? Or asexual species?

(1) you don't have to become an animagus to answer these questions, you just need polyjuice potion.  We already know from Book 7 that you can use polyjuice potion to transform into a person of the opposite sex because Hermione and Fleur both transform into Harry when they go to get him from the Dursley's. (I am a huge nerd, but I also happen to be reading this book at the moment so it's not all super-nerdiness that causes me to know the answer to this question)  So, the answer to your "could you find out" question would be yes, as long as sex happens during the hour you're transformed using polyjuice potion. *

Hmmm.... Polyjuice potion.... I remember it going a bit wrong... with some cat hair in the mix, IIRC...
But an animagus, like Prof McGonagall, can do it with a wave of the wand.

(2) I would presume that an animagus transforms into an animal of the same gender as oneself, unless the animal is inherently hermaphroditic like some kind of worm or if biological gender-transformation is an inherent quality of the species.  We already know that there don't appear to be species limits on what kind of animal you can transform into - like only mammals or whatever - because Rita Skeeter turns into a beetle, and there are fan theories that Dumbledore could turn into a phoenix - in fact, that he could turn into Fawkes (unsupported, IMO) - but we don't know if that applies to limitations like air-breathing animals: if you transformed into a fish but weren't anywhere near water, would you basically immediately die?

If you're going through the trouble of changing into an animal, I'd guess you could take care of creating a suitable environment for it, first...
Or just.... transform into something that could live within your present environment?

* Speaking of polyjuicing into another sex, specifically woman-to-man, while I understand that this is a young adult series and this sort of this wouldn't really be the sort of thing most people would be comfortable with their kid reading about, but Hermione comments on how bad Harry's eyes are when she transforms into him, but says nothing about that the fact that she now has completely different-feeling gentials, specifically genitals that now touch parts of her legs that nothing previously touched.  THAT would be the thing that I think I would most notice if I changed sexes using polyjuice, not how bad my eye sight suddenly became.

I assume that clothing remains in place... so things should be minimally constrained... not dangling and touching the legs
But that would depend on what type of panties Hermione wears. A thong might be too constraining!

I don't know what sort of experience a man-to-woman transformation would have - would the experience of having breasts be similar at all to a scrotum? I suppose it would have to do with the size of said breasts and how impactful they are on the woman's physiology. :S

Scrotum just is.... hanging and lightweight enough not be noticed unless it gets in the way of something.... hmm.... I can foresee someone just transformed into a man and sitting quickly and mindlessly enough for that to become a problem.
Breasts, I guess, are also, usually, not seen as weighing anything significant, right? But I can also foresee a mindless person bumping them into something unexpected...

I have also long wondered why there isn't more illegal polyjuicing going on at Hogwarts, especially boy-to-girl transformations (for, I think, obvious reasons).  If a clever first year study can brew it, surely a NEWT-level sixth or seventh year could.  They have probably made it in potions, or, as Draco does, could have access to the properly brewed potion and be able to steal it.

I see you haven't been allowed in the little back room in the Weasleys' Wizard Wheezes.
Shit, not sure I should have said that in the open forum! Keep it a secret. Good thing Wizards don't know about the internet.

SO MANY QUESTIONS!!!!!

And all they need is a tiny tent - bigger on the inside - to reproduce any environment they wish... just think of the dating potential!
Take your date to a huge canyon, with a tall snow-capped mountain to one side, and a grassy plateau on the other, a meandering river at the bottom. a triple moon overhead and a glass bridge where you can stay for ages!
You wanna go?
