How do rapist and pedophiles work? I can kind of get the sex thing being like a release or whatever. But what about the power aspect? What is going on in the brains and chemically in the body?

I'm no expert but I'm pretty sure you're lumping together two extremely different things.

I know but people hate when one user takes up more and more space in a page. So had to pretty much lump them together. Why are the vastly different physically and chemically. Thanks for the feedbakc.

Um… because a rapist is someone who commits a violent assault, whereas a pedophile is someone with an aberrant sexual attraction. A rapist by definition has committed a violent assault, whereas it’s very common for pedophiles to recognize that they have a serious sickness and refrain from ever attempting to act upon it. I’d wager that is even the majority of cases.

How ever did you see them as being the same?

Well kind of the sex aspect. I was wondering how it chemically worked or biology worked in the body. It just can't be a serotonin high. The brain still has to rush blood to the penis to get hard. But what causes that difference of such a abhorrent acts? Is it serotonin for both? If so how does it differ between places to send it? Is it a combination of blood flow and serotonin working together? Is so how so? Does our bodies do that for any other things?

Yeah and I’m not a professional scientist but there will be far different things going on in addition to the simplest basics of sexual mechanics. Also, rape is not merely a sexual act - the sexual component is in actuality just a means to an end, which is control, power, dominance, anger, defiance, revenge, misogyny, complexes such as inferiority, oedipal - the list goes on. The sexual aspect of rape is its most minimally significant - from the perspective of what’s going on in the perpetrator’s biochemistry etc.

Highjacking the top question. But I asked this before and it get downvoted to oblivion. It is in my opinion a decent question about the make up of a human body and serotoninc and bloodflow. What is wrong with the question? Is it taboo or just people don't like to think about it?

As I said before, I think the few elements that they have in common are the least relevant or valuable in terms of what insight they offer. We know the mechanics of the sexual cycle; but it’s the least informative factor in either of these, and it’s not even always present in the former, which is also not about sex, but merely usually involves it. As for the latter, it is not about the act of sex but about an aberrant sexual attraction.

If you’re asking about these two simply consolidating them, it’s a colossally misleading phrasing, as well as a fallacious association, which presents itself as a deceit right off the bat. You’re truly better served asking these as separate topics, since they actually are.

“How do barbecues and the Space Shuttle work?” They are both about ignition of combustible fuels, correct? If you’ll pardon the reductio ad absurdum, this is the way in which you’re asking about those things, just exaggerated to highlight the fallacy of asking about them together.
