Hi /sci/

What is the evolutionary reason for oral sex?

>> No.2744259

Jesus did it.

>> No.2744263

Exposure to semen of a partner makes Pre-eclampsia less likely as the immune system doesn't react as aggressively.

>> No.2744265

It's an "accident" of evolution.

An unneeded implication.

>> No.2744275

invented by ancient greeks to degrade whores, just so happened it felt awesome.

Hi OP

What is the evolutioanry reason for faggotry?

>> No.2744301

there's no evolutionary advantage. it doesnt help us survive or reproduce. however stimulation of the penis feels good, so thats why we do it

>> No.2744306

The same as the evolutionary reason for masturbation. Cheat codes and exploits of the human body.

>> No.2744317

It's more a cultural reason than anything biological. Humanity likes pleasure.

2. Materials and methods
2.1. Study design of questionnaires
Forty-one consecutive primiparous women with a history of proteinuric preeclampsia and a consecutive control group of 44 primiparous women were asked if they practised oral sex (oral ejaculation) with their partner before the index pregnancy. If the answer was positive, they were asked if they were swallowing the ejaculate or not. No information was asked on quantitative aspects of exposure to seminal plasma. The patients were informed first about the study and the type of questions, before they filled in the anonymous questionnaire.
Definitions used:
Preeclampsia: diastolic blood pressure (K IV) 90 mmHg or more and an increase of at least 20 mmHg compared to the diastolic blood pressure in the first trimester plus proteinuria of at least 300 mg/24 h.
Controls: uncomplicated normotensive pregnancy, birth weight >3000 g.
Because of privacy reasons this group had to be completely different from the group of couples evaluated in the soluble HLA part of this study

1) Mechanism for strengthening relationships (in the brain)
2) Mechanism for stress relief
3) Mechanism for demonstrating social power/relationship things.

All useful

>> No.2744370

>>2744243

Probably because it feels good and as a social species, making others feel good is a useful tool in bargaining. And pleasure probably induces a reduction in stress.

But whatever the reason, I'm just glad it feels awesome facefucking some whore and cumming down her throat.

>> No.2744389

Sex evolved to feel good so people will do it.
Oral sex feels like sex.
Hence oral sex feels good.
Therefore people do it.

>> No.2744435

you misunderstand evolution. for a characteristic (physical structure, mode of behaviour, etc) to be allowed to develop it doesn't have to be of any real benefit to the organism; it just has to not be detrimental.

>> No.2744453

We receive slight pleasure from sucking on things in order to create a desire in children to be breastfed and sustain themselves. It makes a lot of sense for sex, which is associated with the greatest physical pleasure a human can feel, to experiment by adding other types of pleasures.

That sounds plausible.

Well yea, mutations/flukes happen all the time in organisms. The question is why did the mutation stick around.
