Sexual maturity has no role in bringing romance on ones minds as people may feel romance much before they attain puberty. Romance is a psychological application imprinted into your brain which is stimulated even in the childhood itself. There are several social and psychological aspects behind a person's inclinations to fall in love.

Pheromones and Hormones

Most of the species are proved to produce certain pheromones and hormones which attract the opposite sex. Though fewer researches are taken place on human relationships, certain pheromones and hormones are believed to play vital role in attracting people each other and making them fall in relationships. These pheromones are said to be smell-free variants, as recognized by a psychological process not through a biological way.
Oxytocin and vasopressin are the two hormones that promote the emotion of romance in human beings. You might wonder if romance is caused by the presence of hormones and pheromones, then why everybody don't feel the same feelings with all others. The answer is the right combination. A persona may have developed likeness to certain combination of hormones only. This is the reason you will fall in love with certain people only.

Psychological aspect

Love is a psychological element of human relationships, thus it is very difficult to manipulate one's psychology to yield romance in his/her mind. There are certain psychological aspects that may possibly make people fall in love. A feeling of similarity is a major psychological facet that sprouts romance. People who interact for longer period or people who are of the same mind set may develop romance within themselves.
According to psychological theories romance can happen in two ways; compassionate love and passionate love. Compassionate romance is originated from mutual understanding, respect and sharing. On the other hand passionate love is based on intense sexual desires, anxiety and affection. Each love or relationship is fueled by any of these psychological reasons.

Physical attraction

Physical attraction is another reason behind romantic relationships. A normal man or woman is designed to get attracted to the opposite sex at the fulfillment of time. But all the men or women do not find each and every counterpart attracted in the same intensity. They feel some more beautiful or sexy while others less.
The reason is again psychological as the likeness of people is formed in the brain according to the aesthetic and sexual images and ideas a persona has created in his/her mind. The concept of beauty differs from people to people. Some may say that slim is sexy, while other may differ in opinion. As the sayings go, beauty is in the eye of the beholder, attractiveness also vary as preferences of people differ.

Social reasons

  • Society, through life examples and media, fuses the idea of male female relationships into a child and he/she feels an urgency of falling in love within. Society opens more and more chances for girls and boys to interact. This helps them to fall in love easily as things or people most seen become dear to eyes. Today's family atmosphere plays a great role in making people falling in love.
  • Human beings today live in societies where crystal clear laws are defined regarding the human relationships. Society encourages every adult to live in families where they procreate and grow kids as responsible members of society. A child who reaches the age of puberty sees male female relationships all around and gradually he/she too seeks the company of a counterpart.
  • Kids lack parental care as parents may find no time to spare for kids in their busy schedule of life. Thus the only option of receiving care and love is to find out a male/female partner who can substitute all other people. It is a proven fact that less cared kids at home often fall in relationships earlier than others. They satisfy the urge for love in a romantic relationship. This insecurity and unloved feelings often make kids end up with unhealthy relationships too. When the romance is concerned, the social reasons are more visible compared to the psychological or hormonal reasons.
