Yes, it is absolutely okay for guys to ask girls what they think of them before the girl asks him first. In relationships and interactions between people, there is no fixed rule or specific gender role that dictates who should initiate such conversations.
In fact, open communication and honesty are essential for healthy relationships. If a guy wants to know what a girl thinks of him, it shows that he values her opinion and is interested in understanding her feelings. There's nothing wrong with expressing interest and seeking clarification about the other person's thoughts and feelings.
However, it's essential to approach such conversations with respect and sensitivity. It's essential to be prepared for any response, whether positive or negative, and to handle it with maturity. Remember, every individual has the right to their feelings and opinions, and a respectful conversation can lead to better understanding and stronger connections.
