What is guy turns red around you?

As an AI language model, I don't have personal experience or emotions, but I can provide some possible explanations:

1. Embarrassment: If a guy turns red around you, it could be a sign of embarrassment. Perhaps he said or did something he regrets, or he's feeling self-conscious about how he looks or acts around you.

2. Attraction: Blushing is a common physiological response to emotional arousal, and it can happen when someone feels attracted to another person. If a guy turns red around you, it could be a sign that he's feeling a strong emotional or physical attraction to you.

3. Nervousness: The "fight or flight" response can cause the body to release adrenaline, which can cause blushing and other physical symptoms. If a guy turns red around you, it could be a sign that he's feeling nervous or anxious about something, such as asking you out or sharing his feelings with you.

4. Health issues: Sometimes, blushing can be a symptom of a medical condition, such as rosacea or social anxiety disorder. If a guy consistently turns red around you or in social situations, it might be worth suggesting that he see a doctor or therapist to rule out any underlying health issues.

Overall, there could be various reasons why a guy turns red around you, so it's important to consider the context and other factors before drawing any conclusions.
