These two words should never be spoken together -Cologne and Sex. It is a definite erection killer for me, even if the person is drop dead gorgeous. It's like a signal to stay the hell away. I would rather smell BO than cologne on a guy. Ivory soap is ok, but perfumes and any strong scents, not for me. There's nothing more sexy smelling than a freshly showered and dried off guy. The faint smell of fresh sweat, the smell of musk, the smell of his day old t-shirts, the faint smell of Tide laundered underwear. If they could only bottle that. What scents on a guy turn you on? I like that natural clean smell the best. Some guys just naturally smell good I've found.
