Growing up in a religious environment, children learn what not to do sexually. They learn that some practices or ideas, such as homosexuality, lust, masturbation, and pornography are sinful. These ideas are embedded in the minds of children years before they are ready for marriage, so it's no surprise that many religious people have little or no experience with sex and know little about their sexuality.The guilt cycle that results from this training creates a form of self-censorship. Because so many sex acts and ideas are liable to lead to eternal damnation, people have a strong incentive to avoid expressing or discussing secretly held ideas and interests. Fear leads to hidden thoughts and activities and prevents normal, appropriately channeled sexual expression.
