Im not posting an ISO (ChiTown has taught us well)  but what I would like to hear about is any suggestions from anyone who has experienced a true tantric provider.  I just got back from a trip to Sedona, Arizona  and after visiting all of those vortex... the naturalist/ hippie in me is need of further exploration.    From my understanding tantra session are typically longer  90 minutes to 2 +hours to really get the full benefit.
