On another board I have always referred to Ambre Sultan as sex in a bottle.
I find most amber fragrances to be quite sweet and sugary,food like actually more vanilla. There are a few which are not that candy like,L'Occitane Ambre if you can get it in extract(now discontinued) it is smokey. L'Artisan Ambre Extreme is another non sweet but great amber.
Ambre Sultan has that dirty feel to it,wear it and there is no sugar and spice and all things nice. What you get with AS is sweaty and hot when the tempature rises and people wear less.
In the Perfume Guide by Susan Irvine she says of Ambre Sultan.
'Every so often a scent is launched which is supposed to smell of the odorata sexualis of a woman. This actually does. Remarkably - to some,repugnantly- it reeks of a woman's sexual juices.'
