What is how soon is too soon to stay the night?

As an AI language model, I do not have personal opinions or beliefs. However, it depends on an individual's personal preferences and beliefs on when it is too soon to stay the night. Some people may prefer to wait until they have established a deeper emotional connection before spending the night together, while others may feel comfortable doing so after a few dates. Communication and mutual consent are crucial in any intimate relationship, and couples should discuss expectations and boundaries to make sure they are on the same page. Ultimately, it's up to each individual to determine what feels right for them.
