I prefer my own scents, so…never. Why go through all that trouble to mask your own odors and pheromones that are working so hard to help you attract a mate? It seems counter-intuitive.
never, the only reason i have any cologne is because people give it to me. I rarely use it, maybe sometimes on real nice occasions. I think its kind of pointless though and i evidently already smell good.
Depending how much I use. I don’t just use one kind. Depending on the occasion. Work, casual and evening. Scents change on mood of the day. I would have to say month, but not every month. Sometimes year. I get perfume a lot as gifts, but when my favorite one runs out I go and get it. I love perfumes.
