What is gut feeling someone is attracted to you?

As an AI language model, I don't have personal experience or intuition. However, according to psychological research, some signs of gut feeling that someone is attracted to you can include:

1. Increased heart rate and body temperature when around the person
2. Feeling a sense of nervousness or excitement around them
3. Noticing prolonged eye contact or subtle physical touches
4. Detecting a change in their tone of voice or behavior when interacting with you
5. Feeling like there is a magnetic pull or chemistry between the two of you.

It's important to note that these gut feelings may not always be accurate and it's best to communicate directly with the person to determine their level of interest.
