In 1973, the American Psychiatric Association (APA) removed the diagnosis of “homosexuality” from the second edition of its Diagnostic and Statistical Manual (DSM) (Jack Drescher, 2015). Theories of pathology which declared that some internal defect or external pathogenic agent causes homosexuality, have been rejected, such as the theories of immaturity ...

Bottom line: No, Josh Pellicer's work is not based on science, not tested, nor peer-reviewed. However, I will qualify this statement slightly below. Many years ago, I listened to a few episodes of the The Tom Leykis Show, yet another highly sexist advice columnnist for men. Josh Pellicer is not the first, and certainly not the last, in a long line of ...

Pornography laws are a relic of the Victorian era, and not based on any science. Research that can conclusively determine the effect of pornography on children is hard to come by due to the resultant ethical environment. Most research depends on self-reports: Surveys ask adolescents how much pornography they have been exposed to, and attempt to correlate ...

For a non-clinical sample in a study on paraphilic sexual interests, Dawson et al. (2016) report that Fisher’s exact test of proportions revealed that a significantly greater proportion of men reported arousal to activities related to voyeurism, fetishism, sadism, biastophilia, and urophilia compared with women (all ps < .05). A greater proportion of ...

Whilst there have been arguments for the idea that homosexuality has a genetic base or a result of malformations of human development, today's consensus is that homosexuality is a normal variant of human behaviour (e.g. Gonsiorek, 1982) [not resulting in — or a result of — psychological disturbances or maladjustment], and therefore it is not a mental ...

You are quite astute to have noticed the difference between your stated preferences and actual preferences - most people don't. Yes, there has been a fair bit of research on prediction techniques and their effectiveness. In 2008, in a study by Paul Eastwick and Eli Finkel, participants were asked to predict their romantic preferences - what they found ...

This is a trickier multi-part question to adjudicate than you might think. Is Sex A "Need" (Physiological or Otherwise)? Definitions of "Needs", "Motives", etc., are dime-a-dozen. Though I don't necessarily agree with all the ingredients, I like how well explicated the criteria by Baumeister and Leary (1995) are, according to whom a fundamental need should:...

The most straight forward ways to quantify people's sex drive, and hence determine if there's any empirical /objective truth to this disparity, are to measure their self-reported interest in sex (usually by asking "how much do you think about sex?") and also the behavior element (e.g. asking about pursuing sex). Though both of these rely on participants self ...

A bit of background on me: I’m a clinical psychologist and have worked with many sexual disorders, ranging from paedophile, to gender identity disorder. I am however no expert in any of these, so my answer is based on my own clinical experience and reading of the literature. Most of my colleagues, and me, think that the general answer is: no – there is not ...

Jocasta complex syndrome is what you are referring to. In psychoanalytic analysis, the Jocasta complex is the incestuous sexual desire of a mother towards her son. SOURCE

I thought I would edit to add a bit of information. First of all for those who don't know, (I didn't until I looked it up when I saw this question for the first time), the term hebephilia has been proposed to split pedophilia and denote the erotic preference for pubescent children (roughly, ages 11 or 12-14), but it has not become widely used. Along with ...

The idea that homosexuality is disadvantageous from an evolutionary perspective is, in my view, an example of how cultural bias is confused with biological process. While there is evidence that sexual identity has some genetic basis, it is certainly a complicated feature of our identity that cannot be explained by a single gene, and should not be ...

Not by the standards of the DSM-IV-TR. Other answers discuss the case of homosexuality specifically, but the general principles of psychiatric diagnosis also rule out the idea of homosexuality as a mental disorder. The DSM-IV-TR characterizes a mental disorder as "a clinically significant behavioral or psychological syndrome or pattern that occurs in an ...

One factor that should be considered is the culture surrounding casual sex and the social judgments that men and women may experience as a result of casual sex. Conley, Ziegler, and Moors (2012) report a series of experiments conducted on an American university campus that show that women who accept offers of casual sex are perceived more negatively on a ...

What is the difference in the brains for animals capable of these great differences in sexual activity and what part of the brain is responsible for this? In my opinion is a matter of creativity and curiosity. Evolved species try to interact with their ambient in unusual ways, testing different approach to the same "problem" not only to satisfy primary ...

There is at least one somewhat influential theory according to which inhibition of sexual urges, aggressive urges, and many others (such as inhibition of racist behaviour for prosocial reasons) depend on a common pool of resources: the so-called ego depletion theory. Ego depletion means that inhibiting urges draws from a finite resource, and once it is spend,...

To add to these great answers, I'll go on and link to this article. It discusses the DSM (as mentioned in other answers), but also includes a discussion of the homosexual classifications in the ICD (which is maintained by the WHO, as opposed to the APA). The ICD is much broader than the DSM, though. "It is distinguished from the DSM in that it covers health ...

Exactly like you, I would like to begin by saying that I have no animosity nor prejudice against anyone. What I am saying below is not meant to be offensive to anyone, it is just an honest account of what the data in my region says. You wrote: "I can only think of 2 possible solutions ... either a difference in psychological predisposition between the ...

Short answer: It might be genetic. Human sexual behaviour, especially where stigma and taboos are involved, is notoriously difficult to study, so the real answer is that we just don't know. However, some evidence suggests that genetic factors may be at play: A 2008 study compared 112 male-to-female transsexuals ... with 258 cisgender male controls. ...

First of all, it is important to note that the current version (5th Edition) of the DSM — Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychological Association (APA, 2013) — does not recognise homosexual obsessive-compulsive disorder (HOCD) as a mental health condition (Smith, 2021). Homosexual obsessive-compulsive ...

I'm not sure I can give you the data purely for physical attractiveness, but what has been intensively researched is passionate love, which includes physical attraction. Passionate love is usually assumed to include sexual desire, and correlates quite well with rated attraction. As Hatfield writes: Generally, passionate love is associated with the terms “...

While eye contact is certainly important in social interaction I think you should beware pseudoscientific dating advice based on manufacturing "attraction" between men and women. Since this site is about science, let me point to a couple of areas of empirical research looking at eye contact. First, there are quite a few experimental papers showing that (...

This is not my field, but I gave it a quick search. This article seems to speak directly to this question, summarizing and comparing multiple theories to each other. In light of these theories, the article also seems to propose a synthesized theory of the avoidance. Formal citation below. Hope this helps! APA Citation Paul, R. A. (2011). Incest Avoidance: ...

But I'm wondering if any of these hormones are linked with physically intimate non-sexual behaviour, like hugs, kisses and cuddles. Kissing is a little messy because it could be characterised as sexual behaviour. However, oxytocin does has a far more broader role in pro-social and affiliative behaviour than just sexual activity. Here's one reference. It ...
