What is is it normal for my girlfriend to bite me?

As an AI language model, I do not have personal opinions or beliefs, but here is some information that may be helpful:

Biting is a form of physical touch that some people enjoy during sexual or non-sexual activities. However, it is important to establish clear boundaries and consent before engaging in any kind of physical touch. Some people may not enjoy being bitten, while others may find it pleasurable.

If your girlfriend is biting you without your consent or causing you discomfort or pain, it is important to communicate this with her and establish boundaries. It is not normal or healthy for someone to engage in physical touch that causes harm or discomfort.

In any relationship, communication, respect, and consent are key elements to ensure that both partners feel safe, comfortable, and respected.
