Why do many people like porn?
Because porn gives them the freedom to express themselves unhindered.
People who watch porn do so secretly, most of the time.
I think they do it because it makes them satisfy their sexual urge without having to burden or beg anyone for sex.
Sometimes, it happens with teenagers, young folks or those who are not at liberty to have sex freely, or are simply too shy to get a partner.
Subsequently, it becomes addictive.
But I think the number one reason people love porn is the freedom that it gives.
