Prof. Sven Norberg explained that the male protein has miraculous properties. Semen contains the hormone prostaglandins, which stimulate the production of estrogen hormones in women. This means that metabolism improves, skin diseases go away, and breasts get bigger. In addition, when swallowing sperm, a woman gets a certain dose of DNA of the partner, and in a future pregnancy it will help the fetus to take root in the uterus. But that's not all.

Two years ago in Oslo there was a beauty contest for female nursing students. The girls had to have not only perfect looks, but also show that they were smart. The tests amazed the jury: only 5 young ladies out of 300 coped with rather difficult tasks on logical thinking. And they were the ones with the highest IQ. Not only the founders of the contest, but also scientists paid attention to the smart girls. When collecting information, it turned out that these girls began to live early sexual life. Moreover, in the questionnaire they all wrote that they love oral caresses and always swallow their partner's sperm.

– We scanned the brains of women with high IQ and found: the blood-brain barrier (a kind of "filter" between the blood and the nervous system) in them is not as permeable than in less advanced peers – the researchers explain – the blood-brain barrier protects the brain from toxins, germs and excess cholesterol. This means that smart women are not at risk of developing Alzheimer's disease, senile dementia or stroke in the future. But most importantly: thanks to male sperm there is a sharp increase in the activity of brain cells – astrocytes. Such a stimulating effect on brain cells have special hormones and enzymes that are included in semen. So much for an above-average IQ!

So, are you impressed?! You bet! And now, after all of the above, with a clear conscience we move on to the eternal, the most common and ambiguous question for both men and women....

Of course, to swallow or not to swallow semen, if oral sex led to orgasm of the partner – a personal matter of each girl. Forcing her to forcefully do it, against her will means jeopardizing the future of further relationships. Therefore, you need to agree on this in advance with the guy or orient yourself on your sensations.

It is ideal when a man quietly warns that in a few moments he will finish. Say, now you have a little time to decide his further fate of ejaculation, and what it will be – it's up to you!

Not all women like this. If you are not set up for such a completion of the process, it makes sense to warn your partner about it in advance and offer him other options, for example, providing him with a face, breasts, hands for this. It is important not to interrupt the body contact, keep the points of contact (and the more they will be, the better).

For the first blowjob, let him cum on your breasts. Swallowing is not advised, the taste can pleasantly surprise not in the best way. Why is ejaculating on your breasts ideal? It will help you get to know his semen, smell it, touch it, and if you want to, taste it.

Another option is to let the semen flow out onto his penis the moment you stick it out of your mouth. You can hold it against your cheek and let it partially drain onto your face, and that's a great solution too. Letting it drip down onto your face is incredibly arousing for many people.

Alternatively, let him cum in your mouth, but… don't swallow, but gently spit it afterward into a napkin or the palm of your hand. But you don't have to cringe and pretend that it tastes disgusting! It can be noticeably corrupted by this. You don't have to rinse your mouth defiantly: just spit it out and rinse it with water. Chew gum, eat some fruit – and the taste of semen will quickly disappear. There's nothing wrong with it – he cummed in his mouth, he enjoyed it, that's good! And swallow or not – will not affect his physiological sensations.
