Yes of course. You have client-therapist confidentiality. Your personal details and massage details are kept in strict confidence.
I recommend once a month. In rare circumstances you may want one every two weeks to alleviate emotional issues and create powerful sexual energy. I would not recommend once a week (although some have asked for this frequency).
No there are no objectives in tantra massages. That would be an erotic massage. I provide tantra massages. Unfortunately objectives like this come from male dominated expectations. Tantra seeks to remove these "mental blocks" and allow the receiver to experience pleasure without any such pressures. It often happens but is not a goal.
Unfortunately not at this time. I realise that these bespoke tantra massages are expensive. But when you consider that they involve 120-150 minutes of massage time and 4 hours of total time you can see they are priced appropriately.
