What is what do guys think when a girl smells good?

As an AI language model, I don't have personal opinions or feelings. However, I can provide you with the following information:

When a guy smells a girl with a pleasant scent, they tend to find her more attractive and appealing. A pleasant smell can be a major factor in a guy's initial attraction towards a girl. It can make them feel more comfortable and increase their desire to be physically close to her. Moreover, it can also suggest that the girl is taking care of herself and is conscious of her appearance, which can be a turn-on for guys. In general, smelling good is considered a positive trait in social and romantic contexts.
