The feeling of nervousness around someone you like is a common human experience, regardless of gender. When it comes to girls/women getting nervous around a boy/man they like, there can be several reasons:
Fear of Rejection: One of the primary reasons for feeling nervous is the fear of being rejected or not having one's feelings reciprocated. The desire to make a good impression and be liked by the other person can lead to nervousness.
Vulnerability: Liking someone can make a person feel vulnerable, as they are opening themselves up emotionally to the possibility of being hurt or rejected.
Social Expectations: Societal expectations, norms, and gender roles can influence how girls/women feel in the presence of someone they like. They might worry about saying or doing something "wrong" based on what they believe is expected of them in those situations.
Self-Consciousness: People often become more self-conscious around someone they have feelings for, as they want to appear attractive and desirable to the other person.
Overthinking: Overanalyzing situations and worrying about the outcome can also contribute to nervousness. Girls/women might worry about how they come across or if they are saying the right things.
Chemical Reactions in the Body: When we experience attraction or infatuation, our bodies can release hormones like adrenaline and cortisol, which can lead to physical sensations like a racing heart, sweaty palms, and nervousness.
Lack of Experience: For some, the nervousness might stem from a lack of experience in dealing with romantic feelings or being in such situations.
It's important to remember that feeling nervous around someone you like is entirely normal and part of the human experience. It shows that you care about the other person and value their opinion. If you find yourself feeling nervous, take a deep breath, try to relax, and remember that the other person might be feeling similarly. Building a connection often involves vulnerability, and taking things slowly can help both parties feel more at ease with each other over time.
