Genetics and environment shape sexual orientation
On homosexual orientation:
“Overall, genetics accounted for around 35 per cent of the differences between men in homosexual behavior and other individual-specific environmental factors (that is, not societal attitudes, family or parenting which are shared by twins) accounted for around 64 per cent."
Parents shape their children's sexual preferences(Article on rubber fetishism:)
"This basic developmental system, one in which certain salient childhood events “imprint” our psychosexuality, may not be terribly uncommon. In fact, that early childhood experiences mould our adult sexual preferences—specifically, what turns us on and off, however subtle or even unconscious these particular biases may be—could even be run-of-the-mill. And just like the institutionalized rubber-lover, the more carnally humdrum and vanilla among us might also owe our more secret preferences in the bedroom to our becoming aroused, at some point in the distant past, by our own parents, relatives or childhood friends."
Barry McCarthay from
Men's Sexual Health: Fitness Satisfying Sex (it's not an exercise book):
"Fetishes usually develop in childhood or adolescence and are controlled by this combination of high secrecy, high eroticism and high shame," McCarthy said. "It's a poisonous combination.
"There are some men who are extremely erotically charged to full-length boots on women and would not be charged by anything else. Usually, this is due to an experience in childhood that, for whatever reason, gave a powerful sexual charge to that object that the man then masturbated to exclusively."
The Kinsey Institute for Research in Sex, Gender, and Reproduction (article on fetishism and paraphilias):
"Most scientists of sexuality believe that fetishes usually begin early in life, with some incident leading an individual to associate sexual pleasure with a particular object, material or body part. However, Janet Hyde and John Delamater’s great resource Understanding Human Sexuality explains that fetishes can also start after childhood- one study found that it could condition adult men to associate arousal with boots."
Psychologist Dr. Mark Schwartz on arousal patterns:
"Dr. Mark Schwartz, a practicing psychologist in St. Louis, said patients who develop fetishes have often been victims of sexual trauma earlier in life.
"Usually, when someone has a bizarre arousal pattern, there has been something in their past that has made them susceptible to something deviant, or something unusual occurred," Schwartz said.
Schwartz said that individuals who are molested as children by a predator who used a pillow to keep them from screaming might later develop a fetish for erotic asphyxiation."

"Step 1) Go to Japan
Step 2) Open Eyes"
Actually, I have no idea why I said anal sex had become more popular "than oral sex" - I actually had to go back and re-read it to make sure I'd written that. A brainfart, I apologise, the sentence should have just said, "become more popular".
Personally I prefer the blowie unless I want a girl complaining and writhing and being generally uncomfortable during intercourse. Although some guys get off on that.
