Loud sex.

The researchers invited men and women to watch erotic movies. One group enjoyed the "silent" scenes, with the sound turned off, the other could both see and hear the sighs, sobs, groans and gasps of partners. It turned out that those who watched and listened were aroused more and more often than those who simply watched. It turns out that loud sex gives people more pleasure than silent movies. It is curious that British scientists came to the same conclusion. Loud sex is quality sex, they are convinced. And those couples who are silent during such an action simply do not know how to enjoy, not only sex, but also life.
