“There is no purpose or heter to smell her perfume (pashtus).”
Why do you assume that people wear perfume or cologne for the express purpose that other people should smell them for enjoyment? People wear cologne so that they smell plesant. Pleasant does not equal attracting. However, since you are of the opinion that there is no heter (which I will extrapolate to mean that you believe it is assur), can you cite a posek who concurs with you?
