I know exactly what she meant. Men have a muskier scent to them. Like just their clean skin also smells different. & When you combine that with sweat, and wafts of cologne-y bodywash/soaps & yes like the other comment said - deo etc - it's a manly signature
Lol, I just cracked up when miss girl said to one guy's Dong that "it smells like a man," like what smell is that?
