Re: Tunes
For some reason I think "Eyes of the World" and "Scarlet Begonias" would be good tunes to hear during sex. "Terrapin Station" perhaps for those longer more tantric ones.
These are great songs! 
I remember being with a provider down in LA and we had some hard-core Rap music playing, at her request. It was quite an intense, vigorous experience and we were both loud, vocal, and very explicit with our language, almost to the point of being vulgar. It was great.
I find out later that the next day, her neighbor saw her outside and asked her about the "fun" she had the night before. I guess her walls were thin. lol
Peace...
Great question! You know, many moon ago I saw what I would consider to be the closest to a "hippie' provider in Berkeley but she really wasn't a "true" hippie.
I would imagine there would be some in the area but I honestly don't know of any. I find the idea of a 'hippie provider' intriguing and I would love to spend time with one. lol
Peace...
