I thought about a case when a guy had a blood clot at the place of the suction and he died of a stroke.
By the way, the suction was on his neck, otherwise mb could have been pulmonary embolism. In any case, information in 1 sentence is important, and the rest is up to 140 characters.
One Chinese was treated with banks. See what happened to him.
There is nothing harmful in this, if the suction is moderately red (scarlet). On the contrary, local blood circulation improves, which affects the skin in a positive way.
Medical banks confirm this.
In general, something flooded over us, and put the former aspiration 4 on my neck. Big, savory. Already black. Coming home, I heard from my mother the following "lack of sexual shame is a sign of schizophrenia." And "there is no need to show everyone that you are in demand, this is vulgar." And of course the brand "whore".
But I, for example, love sucks))
The author of the question never did banks for himself? Have you never sucked on a bottle and then walked with red lips? Maybe I don't understand something, but the principle is the same. Didn't answer the question, but who cares?
Sucking is dangerous because it can be detected by your partner or parents / teachers (if you are not old enough).
In the first case, at least a scandal is possible: "YOU HAVE AGAIN WITH THE MASK? BUT SAID WHAT AT WORK RETAINED! DOG! ". And flying saucers will not lead to anything good.
In the second, depending on the measures of upbringing, a preventive conversation about promiscuous sexual intercourse, STDs, or simply put in a corner, for example, may occur.
And if you try to suck with some kind of device, for example a vacuum cleaner, you can disable it. Or it will be too powerful and incapacitate you.
A list with an explanation is better.
