Please be aware, the word "sensual" is very often miss used when it comes to massage. Now I am not placing any judgment here, either condemning or condoning the alternative use, but I am just trying to clarify what you might run into out there in reality, if you request a sensual massage. To be quite honest, many people, both providers and recipients, have come to use the word "Sensual" Massage, more or less, as a euphemism for an "Erotic" Massage, or a massage with some type of sexual release involved or "happy ending". In fact this alternative meaning has been so widely used, that the original meaning is often obscured or lost. Just for clarity, if you want to request a sensual massage that is non-erotic, I highly advised that you ask specifically if this provider offers a non-erotic sensual massage, or you might want to use different words to ask for what you are seeking, such as a blissful relaxation massage or perhaps a massage designed to awaken the senses.
Sometimes you may notice that the advertisement is very suggestive, and strongly hints at the real service being offered. If the masseuse is nude, provocatively posed or very suggestively dressed in the photo, than it might be pretty safe to assume that the erotic type of massage is what is being offered. Sometimes it seems that the more blatantly provocative the photos, the less real massage skills the masseuse has. However, if it is really not clear which type of massage is being offered, I would suggest very simply and directly asking if they offer the type massage you are seeking, and really listen to the answer. But keep it very simple and avoid getting graphic. If you are requesting an erotic massage session, I do NOT recommend that you ask if she or he will provide any specific sexual acts, or get into a discussion about how much extra they would charge you. If you try to engage them in any overt sexual talk, particularly in conjunction with money, this will very likely result in the masseuse hanging up on you, blocking you, stopping all communication. Please be aware that this type of talk puts the masseuse into a compromising legal situation. Even engaging in a conversation that involves any specific sexual act for a specific price may put them in jeopardy of being arrested. They may suspect that you are law enforcement trying to trick them.
You may like the picture that accompanies the advertisement, but this may not be enough to determine that this is the therapist for you. Although I personally think it is not ethical to misrepresent yourself, there are providers who use pictures that are not even of themselves, or maybe very old outdated photos from 20 years ago. If physical appearance or beauty is very important to you, be aware that pictures are sometimes very deceiving. The picture you see may or may not be a good representation of who you will be meeting with. If this is important to you, then I suggest that you ask if the picture on the advertisement is an actual up to date picture of the therapist you will be meeting with. If you get a bad vibe at any point while talking to a therapist, that they are not being honest with you, or don't seem to be a comfortable fit, then pay attention to that feeling and move on to someone else.
