It doesn't take much for a man's chest to be noticed.
If he has a good solid pair of pectorals, you will know.
Even if he has his shirt on. A well-toned and muscular chest projects a sense of confidence and self-assurance. A man with a set of powerful pecs is always proud to show off the result of his hard work.
The chest is indeed one of the sexiest parts of the exquisite man's body.
