You can tell whether a woman is faking it by looking at whether her vagina is red or swollen.

Was the climax she just had real? Let's talk about something sad and regrettable: Girls are born with the desire to act (fake GC). After all, cooperation is a difficult task. Besides, you will inevitably pester her to ask about her "feelings after the action" afterwards... However, this era calls for responsible men. As long as you don't want to waste your life and fool your feelings, you should master the "Guide to Identifying Acting (Fake GC)".

Does her face, neck, or chest turn red?

Most people on earth will experience sexual blushing, which is also the wonder of the human body - when a person has an orgasm, the arterial blood will rush to the lower body like a raging sea, allowing the necessary areas to swell up at the critical moment and increasing the sensitivity of the local nervous system. This is determined by heart rate, and even spies cannot control their heart rate freely.

Do her pupils get bigger?

If you close your eyes (or she closes her eyes) at a critical moment, unfortunately, you miss the skills of identifying fake GC left by human ancestors... As early as the Renaissance, Italian girls would drip eye drops made of belladonna into their eyes to use dilated pupils to deceive their lovers. Women still use this trick today: a large number of models use pupil-dilating eye drops or cosmetic contact lenses when shooting commercials.

Is her breathing disordered?

Since breathing is a physiological phenomenon that cannot be disrupted voluntarily, girls are accustomed to using rapid but rhythmic breathing to disguise themselves when acting. In fact, real GC can make them forget to breathe, and even exhale (moan) much more than inhale. This is why humans need to take a long time to breathe heavily after GC.

Is she sweating profusely?

It might be an exaggeration to say that you're sweating like crazy, depending on the position you're in and how long the fight lasts. However, even if the girl doesn't care and relies on you to work hard throughout the whole process, she will still sweat during GC, because the muscles all over the body will tense or contract uncontrollably.

Are her pelvic muscles tight?

My old friends should be familiar with the academic term "pelvic muscle". You can tighten it through the "ani lifting" action. Try it, and you should find that after tightening it, it will relax uncontrollably on its own. It is difficult for humans to keep their pelvic muscles tense without deliberately exercising them. Only during GC, this part of the muscles will move uncontrollably, and this force will make you feel like your little brother is under a tight hoop.

Are her toes curled?

After all, the number of girls who "watch movies" is far less than that of men, and some girls will mistakenly think that the actresses in the porn movies arching their hips from the front means that people will stretch themselves during GC. On the contrary, when doing GC, the first reaction of a person is to curl up, especially the toes. Tip: When you curl your toes toward the sole of your foot, it can also help increase your blood pressure during combat.

Finally, a word of warning: If you find that a girl is always flirting with you in bed, don’t be moved. She did this without considering growing up with you and improving her skills. If she always pretends to take care of your emotions, it only means that this girl doesn't want to spend her whole life with you...
