Tantric Massage is a one way activity, you receive and I give the massage. Tantric Sex is a mutual activity, in general.
I get regular enquiries by email asking whether I do this or that, for example can the client massage me. The answer is the service offered is only what is described here. If I offered sex or something else I would say that.
I enjoy doing what I do, by the way. It is relaxing to give a massage but it is even more rewarding to help a man reach unusual heights of arousal and see him totally pleased with himself.
Many times clients have commented that they have rarely if ever experienced such feelings.
