The prostate massage is by request ONLY. There is no extra charge, it is as an intergral part of the massage.
A glove and lubricant is always used for your protection. I'm extremely gentle, inserting one finger as I continue to stroke, caress and tease your Lingham. Your experience of a dual release; prostate and Lingham in my opinion and feedback always allows for a far more intense full body orgasm experience. Some clients have several full body orgasms prior to the final physical release.
From a health perspective the prostate is an important part of the Tantra massage. In Tantric terms it is said that there is blocked energy in the area and through the massage this is released. In Orthodox terms massaging the prostate encourage's blood flow to the surface which is both nourishing and beneficial.
