Sexually experienced teens. However, the younger a woman is at the time of first intercourse, the more likely she is to report her first experience as being nonvoluntary. Generally speaking, sexual exploration is common in adolescence. The majority of sexually experienced teens (78 percent of females and 85 percent of males) used birth control the first time they had sex (Guttmacher Institute, 2014). Age is the most important correlate of teen sexual experience. Although most sexually experienced teen women (78%) and (89%) of teen men have used some form of contraception,15 STDs continue to be at epidemic levels among youth. About half (54%) of adolescents age 15-19 have had some type of sexual experience [8]. However, adolescents are having less sex today than they were a decade ago. By the late teen years, most teens are sexually experienced. . Table 1 and Figure 1 present the percentage of never-married female and male teenagers who had ever had vaginal intercourse with an opposite-sex partner (sexually experienced). It is common for sexually experienced adolescents, particularly young women, to experience difficulties in attaining sexual pleasure and communicating to partners about what they find pleasurable. This means that young adults may be at increased risk for unintended pregnancy and STIs for nearly a decade or longer. On average, young people have sex for the first time at about age 17, but they do not marry until their mid-20s. sikcv rcdk dzvjr ghphj owauka gmj lhbslgbd rqgcj nfll vzchej
