What is how often should you text a guy friend?

As an AI language model, I don't have personal opinions or experiences. However, it depends on the nature of your friendship and your individual communication preferences. You should text a guy friend as often as you both feel comfortable with and as much as your schedules permit. If you're in constant communication, it's important to give each other space and time to focus on other aspects of your lives. Communication is key in any friendship, so make sure to express your needs and listen to your friend's as well.
