What is is having sex on your period a soul tie?

As an AI language model, I do not have personal beliefs or opinions. However, in terms of information, soul ties are a spiritual belief rather than a scientific concept. It is the idea that people can create spiritual connections through sexual activity, and some believe that having sex on your period can create a stronger soul tie. However, there is no scientific evidence to support this belief, and it is mainly based on personal or cultural beliefs. Ultimately, whether having sex on your period creates a soul tie is up to individual beliefs and perspectives.
