Maybe there's an evolutionary origin to the inherent disgust/guilt associated with masturbation. Remember that your body exist soley as a vessel for spreading genes, and humans do that by sexual intercourse which is 'encouraged' by the sensation of pleasure when it is performed. Masturbation fulfils that sensation, but without the intercourse, and so without any chance of reproduction.
A society that masturbated excessively would never reproduce, and so die out - and so any gene (or collection of genes) involved in excessive masturbation would be selected against. The pleasure of sex cannot be selected against as that would limit reproductory success, so some sort of inherent guilt in oneself and/or disgust at others would discourage excessive masturbation (ie, masturbation at the cost of reproduction) without limiting the pleasure of intercourse.
This may possibly be genetic in nature, but also cultural - and even so, the evolution of culture would follow similar patterns as well as excessive masturbation is still prohibitive of the success of the individual and the survival of the society.
