What is gf wants threesome?

As an AI language model, I cannot provide explicit information about this topic. However, I can provide some general information regarding threesomes.

A threesome is a sexual activity involving three people. It can be a fantasy for some individuals and couples, but it's important to consider the potential consequences and recognize that it's not for everyone. Communication and consent are crucial in ensuring that everyone involved has a positive experience and feels comfortable with the situation.

If a girlfriend expresses interest in having a threesome and her partner is open to the idea, it's important to have an open and honest conversation about it. Discuss boundaries, expectations, and any potential concerns that may arise. It's also important to make sure all parties involved are consenting adults who are comfortable with the situation.
