Read this book if you get a chance.
Kohl, James Vaughn: THE SCENT OF EROS: MYSTERIES OF ODOR IN HUMAN SEXUALITY (New York, Contimuum, 1995)
It is the only book I've seen on the subject so far and it is very interesting. An aspect of Sex and Sexuality many probably do not even consider - and is important. It is worth your time to read it.
Take Care, John H.
