Most of the oils that feature in sensual massage are for the twin purpose of calming but also arousing the mind.
Have you ever come in close proximity to a person who is wearing a very stimulating scent, it can have a very powerful effect of making the people who smell it feeling very aroused and fuzzy headed.
Perfume companies are scientists when it comes to this, and they know what works.
The same is true of aromatherapists who can concoct the most sensual and arousing massage oils.
