What is what does it mean when a guy touches your lower back?

As an AI language model, I don't have personal beliefs and intentions, but I can provide general information that may be helpful.

When a guy touches your lower back, it can signal a few things. The most common interpretation is that the guy is interested in you and flirting with you. It can be a subtle way of touching you and breaking the touch barrier, and it shows he's comfortable being close to you.

However, it's also essential to consider the context in which the touch occurs. Sometimes a guy may touch your lower back just to move past you, help you navigate a crowded space, or guide you somewhere. If it's a casual and brief touch, it may not have romantic intentions.

Ultimately, the meaning behind the touch varies, and it's essential to pay attention to other signs to determine if the guy is interested in you or not.
