You do not need to prepare for tantra-inspired massage in a complicated way. The most important things are a calm mind, good hygiene and enough time that you do not need to rush into something else immediately afterward.
Before the massage, it can be useful to notice whether there are areas of the body that need special attention. For some people the shoulders or lower back hold tension; for others, the most important thing is soft touch and nervous system relaxation.
You can also tell me if something makes you nervous. Tantra-inspired massage is an intimate experience, and it is completely natural to feel a little unsure the first time. Clear conversation before we begin makes the situation much easier.
During the massage, you do not need to perform. You may receive, breathe, close your eyes, sense the body and let the touch guide you slowly. If something does not feel good, you can and should say so.
Good preparation is not about having a perfect plan. It is about arriving with an open, respectful and calm attitude. That is when the massage can become both sensual and nurturing.
