Guilt and shame have been a part of the religion of Christianity since the beginning of the religious movement that we know as Christianity, and there is no part of the Christian experience that is more closely tied to guilt and shame as the Christian experience of sexuality. Depending on the sect of Christianity that you are a part of, guilt and shame may be major players in the psychological and emotional landscape that you build around sexuality, or guilt and shame may not factor into your sexual experiences in any profound way. Each Christian's experience of the relationship between sexuality and guilt and shame is a unique combination of the religious teachings that they have encountered, of their own psychology and background, and of their personal sexual needs, desires and proclivities. Many people who are Christian have happy, healthy sexual lives without feeling guilt and shame. Other Christians have sexual desires and needs that the religious teachings of their branch of the church frown upon. These Christians experience a lot of guilt and shame about their desires, and often do emotional and occasionally physical harm to themselves and others as they try to find solutions to the difficulties that they have dealing with frustration caused by their inner battle between desire and guilt and shame.
There is no truly conclusive and objective way to tell if dealing with frustration related to sexuality and guilt and shame is always psychologically damaging, but the consensus in the scientific community is that Christians who encounter deep feelings of guilt and shame around their sexuality have more psychological difficulties and complications than Christians who do not have desires or needs that compel them to feel guilt and shame based on the teachings of their church. If you feel desires or experience needs that your church frowns upon and feel guilt and shame about your sexuality, you should consider speaking with a professional therapist to get to the root of your feelings. A trained professional will be able to help you as you attempt the process of dealing with frustration around your sexuality, and a good therapist will be able to help you get through your feelings of guilt and shame so that you can live a happier, healthier life.
People who experience guilt and shame around their sexuality are deprived of the happiness and joy that can come from having a happy and healthy sexual life. No sect of Christianity is actually against sexuality in all of its forms, and almost all the different branches of the church admit that there is much more to sex than simply reproduction. Sex is a rich and fulfilling part of life, and if your enjoyment of this aspect of your existence is clouded by feelings of guilt and shame, you deserve better. Don't be afraid to seek trained help as you attempt the process of dealing with frustration. Moving past guilt and shame is a difficult job, and there is no reason for you to have to go through it completely alone and without aid. A helping hand can really make the difference in your emotional and psychological development and can help smooth the path to happier, healthier you.
