In light of religious teachings on sex, unrestricted people often feel they are fundamentally flawed. They are sinful and rebellious against god for having strong urges that go against the church's teachings. If the religious belief is deep enough, a person will not be able to look at his behavior rationally. The result can be a destructive cycle beginning with some religiously prohibited sexual behavior followed by repentance and prayer for a few weeks. Soon biological urges surface again, and he goes back to the behavior, followed by repentance once more. The process keeps him focused on guilt, not on rational ways to enjoy and express sexuality. Every time he goes through the cycle, it makes him feel less worthwhile. At the same time, the only way he can get relief is by going back to his religion.
