Final answer:
Having sex 'for fun' during the Victorian era was considered out of keeping with the social norms of that time, strongly influenced by religious beliefs and the secular moral codes tied to virtue and economic success.
Step-by-step explanation:
The Victorian ideal of sexuality, which focused on procreation and discouraged sex for pleasure, can be understood in the context of Victorianism and the social norms of the time. According to Sigmund Freud, Victorian society was marked by the repression of natural instincts, with strong ties to Christian piety. The ideal of sexuality being confined to the purpose of procreation and within marriage was aligned with the functionalist perspective, which emphasizes the regulation of sexual activity within the family unit to promote marital cohesion and ensure the stability of the family structure. Furthermore, in the Victorian era, there was a moral connection between virtue and economic success, indicating that having sex for pleasure rather than for procreation was seen as out of keeping with both religious beliefs and the secularized moral codes of society.
