SensualityIs simply described as: Relating to or consisting in the gratification of the senses or the indulgence of appetite.
There is a huge discrepancy between sensuality and sexuality. A sensual massage is light in terms of pressure, slow in terms of vigor, long flowing strokes, and will usually use oil or lotion to heighten the pleasure one can derive from the feeling of being touched. It's a method of turning off the fight or flight response and just feeling great from another human's touch. But there is no modality that is taught called sensual massage.
Swedish/Classic/Relaxation massage (they all are the same) are the 3 most common titles for a sensual massage. These are the styles people associate with falling asleep or where quite literally "one's senses are heighten" through what many of us MTs refer to as "fluffy stuff".
"Erotic massage" on the other hand are sexually driven and aren't really massage in the traditional therapeutic sense of the word. Something like Tantric massage or Nuru massage are sensual in theory, but because they cross the blurred line into sexual or sex-like acts, they could be better aligned with sexual services more than an actual massage.
A Swedish or Relaxation massage would most often be the sensual precursor to a "Happy Ending", but the addition of the sexual act makes it more of a sexual service with a massage, even though there was the massage was the agreed upon service.
Chicken Wings: Think of it this way... If you go into a Hooters and a beautiful woman takes your order and brings you chicken wings and you eat them and leave, you have paid for a sensual food service.
Yet if you go to a strip club, order wings and get a blowjob from the stripper in the back room, you have paid for a sexual service that just happened to include chicken wings...
Suffice it to say, eating chicken wings can be a very sensual experience but if you shove a chicken wing up your arse to stimulate your prostate, then it is a sexual experience that just happen to include a chicken wing. I hope my example serves you well.
