Reddit reviews Sex, Murder, and the Meaning of Life: A Psychologist Investigates How Evolution, Cognition, and Complexity are Revolutionizing Our View of Human Nature

Ok, this is a serious topic, and I commend you for your courage in posting it. I will thus give you a serious analysis that I hope will CYV. I must first state to any and all who are reading this reply, present or future, that I am offering up an expository and scientific response to OP's stated view for the purpose of insightful discussion. This response does not, in any way, form, or fashion, endorse ANY social or political views on how pedophiles ought to be dealt with beyond what all current laws and common social practices dictate.

ok, with that out of the way...

Starting with the ground-breaking work of Dr. Kinsey in the 1940s and 50s, we now have a vast and detailed body of scientific knowledge about human sexuality. Before Kinsey, human sexuality was understood to be "girls like boys and boys like girls" and this fit nicely with all evolutionary and psychological understanding of the human experience... in fact, anything that deviated from this maxim was considered a psychological disorder and thus was thought to be caused by factors that were extrinsic to the individual (for example, gay men were thought to be gay because they were "mothered" too much and lacked "fatherly discipline" in their youth.)

But paramount to his research, and all the research of human sexual behavior that followed, is the surveyed documentation that descriptive human sexual desires (read: "kinks" or "turn-ons") are not solely derived from, nor explained by, environmental influence nor psychological complexes like the "fear of death" that you mentioned.

Consider individuals with a foot fetish. Is there a clear evolutionary concept explains this? Further, if you take a sample of all individuals with a foot fetish, you would find that your sample is, for all intents and purposes, identical in character to a sample of all living human beings (save only the fact they have a foot fetish.) As far as we know, nothing MAKES a person sexual turned on by feet... they just "are."

Another example. Some, but not all, men are attracted to large female breasts. On initial examination, this has evolutionary grounding in that men ought to be attracted to women capable of nurturing children. However, an equally sized population of men are attracted to small to medium sized breasts. And what of the size of female posteriors? Or the height of potential female partners? Or the body size of potential female partners in heterosexual men? Again, results vary significantly across populations so much so that both environmental and individually unique psychological factors can be ruled out as a source cause.

We should then look at homosexuality. It is well understood that there are no known environmental or individual psychological condition factors that predict homosexuality. So "nurture" can be ruled out as a "cause" of sexual attraction to the same sex, and as far as we know, there is no "cause" that transforms an individual from a so-called "default state" of heterosexuality. Baby, you were born that way! Right? Well... not exactly. While there are some genetic predictors of homosexuality, these predictors are never fully reliable in predicting gender biased sexual orientation... even in homozygous twins!

And this is to say nothing of other strong and prevalent sexual kinks such as BDSM, stockings, incest, vinyl, quicksand (yes, this is a thing), cheerleaders, dadbods, vampires, waifus and husbandos, lipstick, smoking, glasses... the list is VAST!

So do our unique sexual desires come from Nature or Nurture? or some combination of both? As far as the best science is concerned, the answer is maybe and neither of these. maybe and niether of these.

Thus, we turn to Pedophilia. This is not my scientific field, so there are surely better people to address this question than me, but what I can tell you is that research is VERY sparse. To study this would be career suicide for most research psychologists. Just go to Google Scholar and type in 'pedophilia' and you will see for yourself.

What I can tell you, is that it is most likely that pedophelia most likely follows the same pattern as all of the other sexual preferences and kinks that the field has studied in depth. If this is the case, it is most definitely the attribute of being a child or appearing child like that turns the pedophile on, and not a psychological desire to vampirically "drain energy" from vibrant youthful sources as you state in OP. We do know at least that there are strong differentiations in individuals who exhibit these preferences. They are:

• Pedophile -- an individual who is dominantly sexually attracted to pre-pubescent children
  
• Hebephile -- an individual who is dominantly sexually attracted to pubescing adolescents.
  
• Ephebophile -- an individual who is dominantly sexually attracted to individuals who have recently completed pubescence.
  
  For each of these descriptors, we know that the potency of the individual's sexual arousal strongly falls off between each group. So, a typical pedophile is strongly sexually attracted to pre-pubescent children and they might be moderately-to-slightly sexually attracted to pubescing adolescent (the domain of a Hebephile) and mildly to not-at-all sexually attracted to a fully, yet recently, pubescent adolescents (the domain of a ephebophile) and definitively not-at-all sexually attracted to adults. We also know from anecdotal evidence that pedophiles typically exhibit signs of their sexual attraction to pre-pubescent children during their own puberty. We also know that these individuals tend to be male, but are not exclusively male.
  
  It is also important to note that multiple studies have dispelled the age-old myth that males are predominantly attracted to younger partners. For neurotypical heterosexual males, peak attractiveness of female partners is measured to be about age 23, which strongly correlates to peak fertility. In other words, a 15 year old boy is most likely to rank a 23 year old female as "most attractive" when all other factors besides age are controlled. Strangely enough, this trend is also observed in homosexual men!
  
  Ultimately, your conception of pedophilia as an attraction to "youthful energy" or "pureness" does not fit with the data, insofar as "pureness" is a descriptor that an adult could, in theory, imbue. There is still much to be learned and I hope more researchers will find the courage and capability to study this further!
  
  And, as far as any suggestions for therapeutic interventions for pedophiles/hebephiles/ephebephiles goes, I respectfully decline to contribute input as my expertise is no where near sufficient to put forward meaningful contribution.
  
  I hope this helps!

I'll give some advice because I've had some similar situations in my own life. I'm using "you" but...if the OP is for someone else or background, this is meant to be general advice.

"Therapy" is a great panacea for an answer, but most therapists aren't really equipped to deal constructively with multiple personalities. There is a tendency to see multiples as an illness...thus "identity disorder."

If you read Douglas Kenrick you come to the understanding that nobody is a "single identity." It is just that most people in society have the cracks plastered over seamlessly.

I'd recommend the Kink Aware Professionals list for a start. Look for professionals who will do therapy online (Skype, or even email) and ask questions about their attitudes toward multiple personalities.

In the meantime, you may want to try some self therapy. Writing letters to your other identities that explain things to them can be helpful. Getting them to communicate. Trying to see if you can get more than one of them to manifest in your mind at the same time and discuss what triggers them. I've seen some very hostile and self-destructive personas settle down when they became involved with the others.

In my experience many people have found they can get their personalities to talk more amongst themselves, and communicate better, and that tends to curb the most extreme aspects of their acting out. Understanding they're part of a group and not alone.

Hypnosis can be a good tool for this, though I think most professional hypnotists would be reluctant to touch this sort of situation, or want to "fix" it in the wrong way. I've known a number of scene tops who worked through hypnosis with bottoms who had multiple personalities, but it is not something I would try without someone who has both prior experience and excellent scene recommendations as a safe and consensual partner.

You could try self-hypnosis, using audio recorded on a phone, or just meditation techniques. I think for anyone whose mind works this way, trying to introduce some meditative/reflective practice to create a calmer center can be useful.

I've also gotten some anecdotal suggestions that Ayahuasca may be helpful in allowing overall perspective, but I can't speak for that personally. I do know it can be a powerful experience in regards to depression.

Here's one option. Not sure how useful it will be for setting new goals, but it covers meaning throughout one's life.

The desire to experience the nuances/differences of all five senses, particularly sensuality, hearing, and taste.

An exercise in gradually lowering the sound of a recording and still understanding the meaning.
