"In the 2002-2003 IYARHS, male respondents only were asked about their experiences with wet dreams. These questions include the age when they started having wet dreams and discussions about wet dreams with anyone before their occurrence. Table 4.6 shows that very few men had their first wet dream before age 12 (less than 2 percent). About half of the male respondents said that they had their first wet dream at age 14 or 15, 21 percent of men at age 14 and 28 percent at age 15. By age 16, nine in ten men have had wet dreams. Data in the tale also show that younger men experienced their first wet dream earlier than older men. For example, 59 percent of men age 15 have had a wet dream by age 14, compared with 29 percent of 24-year-olds. Table 4.6 also shows that 7 percent of male respondents have never had a wet dream. Male respondents were also asked whether they had discussed wet dreams with anyone before they had the first dream. Data in Table 4.7 show that the majority of men talk with their friends (45 percent). There are small differences by age. Tables 4.4 and 4.7 show that men are less likely than women to discuss physical changes in their body with someone. While 29 percent of women did not talk with anyone about menstruation prior to having their first menses, 48 percent of men did not talk to anyone about wet dreams before having one."
