What is when a guy notices your nails?

As an AI language model, I don't have personal experiences or emotions, but I can provide you some general information.

It is common for guys to notice a woman's nails, particularly if they are painted or manicured. Some guys find well-shaped and painted nails to be attractive and can be impressed when women take good care of them. However, not all men pay attention to nails, and many do not consider them a significant factor in their attraction towards a woman. Ultimately, the importance of nails varies from individual to individual, and it is essential to focus on your personal grooming preferences rather than pleasing others.
