What interests me is the idea I've been hearing about a lot that sex should be used only for reproduction. The justification that I've heard for this statement is based on the idea that any other sexual activity that invlolves any kind of contraception is preventing a possible person from coming to life and possibly causing psychological harm for the people that engage in sex and also their future children as they might be carrying guilt (this I have heard from a psychologist, that uses Hellinger's method of phenomenological psychotherapy). Also other arguments that I have heard from other sources are saying that there is no other benefit in engaging in sexual activity apart from possible children and pleasure. As pleasure is considered to have a very short term value it is said that there is no rational reason to have sex when we do not want to reproduce, because the risks and the consequences are larger than the value of pleasure. Humans according to some theories have to sublimate their sexual energy to spiritual activities or any other self-realisation, because the modern society is degrading wich is caused by the consumer tendencies and pleasure seeking. That causes many modern world problems. It was claimed, that all ancient cultures had the same beliefs about sex for a reason, and that those values were universal. Also the principle of genetic teleology was mentioned. Sometimes I get mixed up understanding wich arguments about this should be called rational and justified by any logical or empirical evidence and how much of this is based on dogmas and plain beliefs. So, can such argumentation be taken seriously when trying to figure out this sex question? Also, does the possibility of God's and the human spirit's or soul's existence definately implies that sex is only for reproduction? What would be the opposing arguments against this idea and what would be the rational arguments for this?
