Introduction The topic under discussion is human sexuality, which is a subject that generates a lot of controversy. It is essential to understand norms for sexual behavior and how society can maintain these norms. In this regard, one must discuss teen sex as well as premarital sex, and relate to this to the limitations that people place on human sexuality. Analysis The topic is a critical one because sex is related to vital parts of human organization, such as, family, procreation, and companionship. Furthermore, sex has grave ramifications on other people as well as society in general. Religious guidelines, moral principles, taboos and legal repercussions are indicative of the gravity of this topic. Additionally failure to abide by certain rules leads to unwanted consequences among concerned parties. It is vital to trace the sources of influence on current perceptions of human sexuality, and then establish how those norms ought to be maintained. In order to understand the limits of human sexuality, one must look through the barriers to eligibility in sexual relations. Sometimes, an individual’s gender governs their sexual choices.

Therefore, sex with underage persons or among them is frowned upon because these individuals do not have the psychological maturity to give consent. Additionally, violence in sex is highly frowned upon because one of the parties is held against their will, so no consent exists. It should, however, be noted that people have not completely disregarded the relevance of marriage in sex (Bramlett and Mosher, 2002). Single parents, who have several sexual partners during a child’s development, have difficulties in teaching them about sexual morals. Such children will imitate their parent’s behavior, and may start having sex in their teens. Society’s lack of commitment on premarital sex has blurred the lines on sexual limits, and thus perpetuated teenage pregnancy or even violence. Studies indicate that sixty six percent of all pregnant teens engaged in sex owing to abuse from older males (Potera, 2009). Usually, these activities took place because of parental absenteeism. Such parents are single and have to focus on economic
