Go look up what "love" is scientific. You're now being dismissive. It's a clear indication you don't know how the human body works. I provided resources and a general definition of "oxytocin". You're literally now just being naive as a refusal to learn or even research. This is my last reply.
Hormones have influence on emoitions as well as rely on hormones to maintain stability aka "Storotin". Humans rely on hormones to function properly.

Serotonin, dopamine, and oxytocin are often referred to as the brain’s happiness trio, playing crucial roles in regulating our mood, emotions, and overall well-being. These three neurotransmitters work in concert to influence various aspects of our mental and physical health, from our sleep patterns to our social interactions.

Oxytocin, often celebrated as the ‘love hormone,’ plays a pivotal role in various aspects of human behavior and social interaction. Discovered in the early 20th century, this neuropeptide is synthesized in the hypothalamus and subsequently transported to the posterior pituitary gland, from where it is released into the bloodstream and the central nervous system. It is primarily known for its role in childbirth and lactation; however, its influence extends far beyond these biological functions.
In humans, oxytocin is implicated in fostering social bonding and enhancing emotional connections. Research indicates that this peptide significantly modulates trust, empathy, and attachment between individuals. For instance, its release during interactions such as hugging or bonding experiences can intensify feelings of closeness and enhance interpersonal relationships. Furthermore, studies have suggested that oxytocin administration may increase pro-social behaviors, making individuals more inclined to form connections with others.

The only social concept of sex for procreation is mainly found in religion and certain cultures.
Biology and nature in the term "sex for procreation" is a nuance. Their is no strict binary code to state sex is solely for reproduction. Many animals including us perform sex acts beyond the reason for babies. Masterbation, oral sex, social bonding ect...
There even animals that don't need males or sex for making babies. Called "parthenogenesis"
Humans literally perform sex acts beyond baby purposes.
