In over 30 years of punting, both indies, agencies, parlours etc, I can't recall any WG wearing perfume.
Its definitely clean and au natural for me.
There have been occasions when due to poor hygiene or infections etc, I've been put off by unpleasant odours, but on those odd occasions, perfume probably wouldn't have masked the smell anyway.
Unless I was arranging an overnight or dinner date (which was quite rare), I wouldn't have expected the WG to wear perfume.
In fact, as I have mild asthma, strong perfumes could make me slightly wheezy.
I love women, and in my view, it's impossible to beat the natural smell of a woman.
In fact, I don't like anything unnatural in a women.
