When we’re masturbating, our perception of what is sexually attractive and desirable changes. This all happens through my favourite part of the brain: The Prefrontal Cortex. Its the part of the brain that focuses on personality and creativity. Research has found that heightened sexual arousal achieved through masturbation can make almost anything and anyone seem more sexually appealing. Interestingly enough, these findings tell us that sexual arousal changes our perceptions of the world around us. Which is pretty crazy!
