00:00Hey, Psych2Goers, welcome back to our channel.
00:03How much do you know about sex?
00:05There are a lot of interesting psychological facts
00:08about sex you may not know.
00:10We've talked about this topic before in our video,
00:12eight psychological facts about sex,
00:14but now we have six more interesting
00:16psychological facts about sex
00:18you'd likely be surprised to hear.
00:20Here they are.
00:21Number one, it takes less than a second
00:23for your brain to decide if someone is sexually attractive.
00:27How long does it take for you to realize
00:28whether or not you're sexually attracted to someone?
00:31Well, according to a 2008 study published in NeuroImage,
00:34it takes half a second for your brain
00:36to decide whether or not someone is attractive.
00:38The author of the study, Stephanie Ortegu,
00:40explained in an interview that they found the brain knows
00:43who we desire and when we desire before we are aware of it.
00:47Researchers also found that it may take our brains less time
00:50to decide if someone is unattractive.
00:52In a hurry much?
00:53Number two, females can alter their voice to sound sexier.
00:59What does your sexy voice sound like?
01:00In a 2013 study published
01:02in the Journal of Nonverbal Behavior,
01:04researchers Susan M. Hughes, Justin K. McGilsky,
01:07and Marissa A. Harrison had 40 participants.
01:1020 male and 20 female manipulate their voices.
01:14For one part of the study,
01:15researchers had participants attempt to sound attractive.
01:18The study states that among them,
01:20we found that when trying to sound sexy or attractive,
01:22both sexes slowed their speech and women lowered their pitch
01:26and had a greater vocal hoarseness.
01:28The results?
01:29When subjects manipulated their voice to sound attractive,
01:32researchers found women were able to alter their voices
01:34to sound more attractive, simply counting from one to 10.
01:38Men, on the other hand,
01:39were rated as sounding less attractive
01:41when they throw on their sexy voice.
01:44Number three, cuddling after sex can increase satisfaction.
01:48Who doesn't love cuddles?
01:50But apparently cuddling after sex is the time to do it.
01:53A 2014 study published
01:55in the Archives of Sexual Behavior found that cuddling,
01:57kissing, and affectionate talking after intercourse
02:00can increase a couple's bond and sexual satisfaction.
02:03When researchers asked partners to cuddle more after sex,
02:06couples who did so reported greater levels
02:08of relationship satisfaction and sexual satisfaction.
02:11They found this notably more true
02:13for those couples with children.
02:15Researcher Amy Muise notes that when people think of sex,
02:19they tend to be focused on intercourse and orgasm.
02:21This research suggests that other affectionate aspects
02:24are important for sexual and relationship satisfaction.
02:28Number four, not everyone desires sex.
02:31As you may know, not everyone desires sex.
02:34This is especially normal for those who are asexual.
02:37Asexuality is a sexual orientation
02:39where someone doesn't experience sexual attraction
02:41towards others, or they may experience little desire
02:44for sexual encounters.
02:46Everyone is different, so it's seen more on a spectrum.
02:49When it comes to sexual desire,
02:51your normal may be different from others.
02:53Sex therapist and New York Times bestselling author
02:56Ian Kerner said it best, explaining that normal
02:59is such an elastic word.
03:01It depends on what your baseline libido is.
03:04Number five, sex before a stressful task
03:06may lower your level of stress.
03:08Got a big test tomorrow?
03:10Well, let's look at the research.
03:12A 2006 research study published
03:14in the journal Biological Psychology
03:16had subjects take part in stressful activities.
03:19These included giving a public speech
03:21or taking a difficult math quiz.
03:24Subjects who had sex before the test
03:25had lower blood pressure and lower levels of stress.
03:29This was when compared to those who had no sex,
03:31those who masturbated,
03:32and those who had sexual contact without intercourse.
03:35The study even claims that penile vaginal intercourse, PVI,
03:39but not other sexual behavior is associated
03:42with better psychological and physiological function.
03:45And number six, sex can alter your pain perception.
03:50According to some research,
03:52sex may alter your pain perception,
03:53making you feel less pain.
03:55The section of the brain called the hypothalamus
03:57releases the feel-good hormone, oxytocin,
03:59also known as the love hormone during orgasm or arousal.
04:03Researchers at Rutgers University
04:05found that this release of oxytocin
04:07may help women feel less pain.
04:09This can be especially true during menstruation.
04:12Another study published
04:13in the Bulletin of Experimental Biology and Medicine
04:15found that extremely low doses of oxytocin
04:18reduce pain sensitivity in men,
04:20lowering one's pain threshold by 56.5%.
04:24Wowza.
