Adolescence, which is the years from puberty to adulthood, can be split into three steps: early teens, generally ages eleven to fourteen; middle teens, ages fifteen to seventeen; and late adolescence, ages eighteen to twenty-one. In addition to biological progress, the mental and the social growth are the key intellectual developing tasks embraced in these years. The essential goal of these functions is to establish one's personality and to get ready for adulthood. Further, most boys and girls arrive at puberty observing the world around them in definite terms: things are either moral or immoral, amazing or terrible. They hardly set their views ahead of the presence, which clarifies the younger teenagers' incapability to reflect on the long-term outcomes of their engagements. Furthermore, by late adolescence, many teenagers have come to recognize delicacies of the conditions and thoughts and to foresee into the future. At this phase, their capability to resolve intricate problems and to detect what others are contemplating has improved significantly. However, they are comparatively inexperienced in life, and the older youngsters employ these newfound abilities impulsively and can act without reasoning (Healthy, 2018).

Through most of the infancy, individuals develop at a stable tread of about 5-10 cm and 2-3 kg yearly. Nevertheless, in the early stages of adolescence, most persons experience another drastic alteration, often called a development spurt. In girls, this normally arises at around the age of 10-13 while in boys; it emerges between the ages of 12-15. Moreover, advancement is prompt in this period, a girl can add about 9 kg per year, and the boys can add around 11pounds. A significant physical transformation in adolescence is the appearance of the secondary sexual features. The girls develop a surge of hypodermic fat rounding of the physique; the breasts and the pubic hair grow during puberty. For the boys, the penis and the testes enlarge the pubic hair starts to develop, the voice deepens, and the muscles develop and strengthen through this phase. At the age of 13 to 14 years, most boys undergo ejaculations or the wet dreams. There are substantial hormonal growths, owing to the enhanced production of estrogen in girls, and androgen in boys. The youngsters are now moving towards their advanced shape and size, but the stride of progress differs significantly around the persons. The difference in the pace of expansion leads to complex results. Those adolescents who develop early manage to have an advantage in that they are treated more of as adults (Durkin, 2001).

Equally important, puberty is certainly the period in which sexual progress, curiosity and familiarity rise. The amplified concern is caused by the sustained attention and consciousness of the body modifications and the arising hormone intensities. Hormonal signs from the brain to the gonads instigate puberty. These hormones arouse the development and function of the brain, breasts, hair, sex tissues, and the skin. The most apparent being the facial hairs in males and breast growths in females. The teenagers at this period get ready for adult roles through courting and some degree of more close contact with their peers. For both young men and women the testosterone level, appear to influence the sexual activity. Once again, focus on the genitals and curiosity steers sexual relationship among the associates. Kinsey's statistics specified that among the individuals reviewed 92% of the males and 62% of the females recounted having masturbated. Further, there is an increase in masturbation in boys between the ages of 13 and 15, with about 85-90% of the young men between these ages describing masturbation. At around this age, the boys essentially masturbate to orgasm. The Kinsey analysis discovered that masturbation in women climaxes at the age of 30 and stays even from this stage. The median age at the first intercourse is 17.4 years for the girls and 16.9 years for the boys. For those who are sexually vibrant, the first sexual intercourse is a major conversion both mentally and socially. Moreover, there seem to be a gender variance in the involvement of the first sexual intercourse with the young men stating more leisure that is sexual and less guilt than the young women (Topics in human sexuality, 2007).

Besides, adolescence comprises the teenaged years from 13-19; however, some girls arrive at adolescence at the age of 10 or 11, and so become adolescents before they turn out to be teenagers. There are also various individuals' ages 20 to 21-years who endure the unveiling of many of the signs of puberty. It is presumed that adolescence is a very challenging phase in life, with the teens being extremely strained and moody. The reason is that they have to manage the vast alterations in their lifetimes. Some of these modifications are in the sexual activities following teenage years. In this period, the teenagers undergo identity diffusion, which entails a stout feeling of doubt. The teens encounter identity catastrophe because they do not recognize who they are, or where they are going. The women acquire a sense of personality later than males, apparently because they understand that their individuality and the social eminence will be determined very much by the kind of man they prefer to marry. Adolescence persists for numerous years, and the identity calamity conceivably progresses at any moment within the adolescent years. However, the individuality predicament is more likely to appear in late puberty than at any earlier time (Ensenck, 2004).

According to (Fingerman et al., 2008) by the late adolescence, the youth in the United States reveal substantial concern in their friends and devote their leisure time to them. Throughout the pre-school years, the youngsters gradually discern friendship and less close companions. The indication of the social abilities with the peers in the initial years seems to foretell the consequent social conducts in later childhood. Furthermore, as the young individuals turn into the teenage years, the relationships with their peers become extensive as well as rigorous. All around the development of this life phase, the teens devote most of their time with the equals and less time with the family members. The building of intimate affairs develops and becomes intricate, the teenagers learn to steer dyadic relationships with their colleagues and sexual spouses, and their status is centered on the friend's cliques. Moreover, more so than in childhood, adolescents are considerate to their equals' and the reputation ranks. The word 'reputation' is instilled with a different connotation than it had in the previous years. In juvenile, popularity asserts to how much one is admired, while in adolescents, it assesses one's status of inspiration over the friends. Furthermore, because of the comparatively increased level of hostility the popular teens demonstrate towards others, they are not the best-liked peers. The violence fluctuates over the period of adolescence from physical to oral. Further, such hostility is exercised to advance one's rank among the equals. The association between popularity and aggression motivates two kinds of non-intimate peer bonds that entities must confer throughout adolescents.

To conclude, adolescence evolves at the ages of 11 to 21, and during these years' individual experiences psychological, and physical growth, that enables one to prepare for adulthood. In adolescence, the person experiences stress because of the emerging body changes and the capability of solving complex issues. The teenagers are not focused on the future because of the identity crisis since they do not comprehend their purpose in life. In this stage, their peers influence them because they spent most of the time with the peers than with the family members. The isolation is momentary, and the family relationship can become less conflicted and more intimate during the late adolescence.
