"Males who have nocturnal emissions usually receive no prior sexual information (Shipman, 1968). The cultural assumption is that there is no need to explain male sexuality prior to puberty; its first evidence will be a pleasurable dream with the tell-tale evidence found in the morning (Shipman, 1968). This contributes to the postponement or avoidance of any discussion of the physical or emotional manifestations of puberty and/or the occurrence of nocturnal emissions (Masland, Rigg, Shochet, vlestman, & Lopez, 1980). There are males, however, that never seem to experience nocturnal emissions. Males who have not experienced nocturnal emissions usually receive no prior information regarding this possibility and are unprepared for this phenomenon. No mention is made in the media or the literature about males having erotic dreams to orgasm without the accompanying ejaculate. Because of this informational void, trauma, confusion, and feelings of abnormality are more likely to beset the male who has not experienced a wet dream."
