The respect of the body and intimacy are essential and even during more in depth treatments, the touch is without amiguity, profesionnal and non intrusive.
Of course each has their own relation and understanding of intimacy so a discussion prior to the massage is key to rescpecting the boundaries and all your questions will be answered on this topic.
Specific underwear and body covering is available if required.
Respect should be mutual and no irrespectual behaviour will be tolerated.
