Humans typically start thinking about romantic relationships at various stages of life, often during adolescence or early adulthood when they begin to experience changes in their emotions and social interactions. The reasons for wanting a boyfriend or girlfriend can vary widely from person to person. Some may seek companionship, emotional support, or the experience of love and intimacy. Others may be influenced by societal expectations, curiosity, or a desire to explore their feelings and emotions further.
It's important to note that everyone's journey in terms of relationships is unique, and there's no specific age or timeframe for when these thoughts and desires might arise. The most important thing is to approach relationships with honesty, respect, and understanding, ensuring that any romantic involvement is consensual and based on genuine connections and mutual interests.
