No, it is not inherently bad for girls, or anyone for that matter, to talk to many people of any gender, including guys. Communication and social interaction are essential aspects of human life, and people should feel free to engage in conversations with whomever they choose.
It is essential to avoid making generalizations or imposing double standards based on gender. Talking to many people, regardless of their gender, is a natural and healthy part of developing social skills, forming friendships, and building connections with others.
If someone is respectful, honest, and communicates boundaries clearly, there should be no issue with talking to multiple guys or girls. Building a diverse network of friendships and relationships can be enriching and help individuals learn from different perspectives and experiences.
However, it is essential to remember the importance of setting personal boundaries and being mindful of one's actions and intentions to ensure that communication remains respectful and genuine. Everyone has the right to choose whom they want to interact with, and it is essential to respect each individual's choices and decisions.
