A new German study says that porn may have adverse effects on your brain!
Researchers say men who watch a lot of porn usually have smaller striatum (that's the area of the brain linked to motivation and rewards). The connection between the striatum and the prefrontal cortex (responsible for behaviour and decision-making) also decreases when watching increased amounts of porn.
A survey by the University of East London said 97% of boys aged 16-20 have viewed porn, and girls of the same age: 80%. One in three women regularly watches porn, and 70% of men 18-24 visit porn sites at least once a month.
There's a significant number of students, boys in particular, for whom it is quite a frequent behaviour. At that age, they're still developing their sexuality, their ideas of what's normal in sex, and ideas of what's appropriate in relationships. Heavy exposure to pornography can be problematic in all of these areas.
So the nuns were right - pornography DOES sink the brain! Mind you, perhaps those with smaller brains are more attracted to porn. And, if their brains are in their dicks, they may be very very small brains indeed...
