There are many reasons why female college students generally don't take the initiative to chase boys, including:

1. Different social circles: The social circles of girls and boys may be very different. Girls are more likely to join campus sports clubs, participate in activities and become friends rather than lovers, while boys are more likely to join brother clubs and participate in football or basketball games.

2. Different values: The values of boys and girls may also be very different. Girls pay more attention to interpersonal relationship, family and friendship, while boys pay more attention to career and achievement. So girls may be more willing to connect with people who share their own values.

3. Experience: Female college students may not have the experience of pursuing boys. On campus, the relationship between boys and girls may be simple, but outside the school gate, the situation may be different. Girls may be more cautious and consider the risks and consequences of pursuing boys.

But this does not mean that all female college students will not actively pursue boys. Everyone has different personalities and ideas, and different people may have different performances.
