I have been reading that the "P spot " is to men as the G-spot stimulationvis to woman.  I want that experience vs the routine hand job or blow job.   Two questions; 1) is a real / great P massage a life changing experience if done by an "expert" and 2) if yes, are there some recommended experts in the dc area?

I can't give you any help in the DC area, but I can tell you that a P massage is as good as it gets and if you haven't had one yet, there's no time like the present to do so!  It's the best!

A bung hole massage may be the best for you but it ain’t the best for me.

 
Nothing going up Jack’s ass without a court order and a huge fight. LOL

My hostess was working with me to get #2 but time was running out. I said that I don't think it's gonna happen. She disagreed. While sucking away, she slipped a finger up the other end and - shazam! - she was right!

It might have been the surprise factor, but I usually prefer to use that exit as an exit and not reverse the flow of things. (I did have an annual physical not too long ago and it included a digital exam. When I saw the size of the slide rule on his desk, I was glad he didn't go analog!)

She's talking about a "prostrate" massage.  They aren't the same thing.  She just wants you laying down.  

 
I agree with you on back door entry of ANYTHING.  I have a tattoo just above my butt crack that says, "Exit only."  Lol

Many years ago was my first time, and it was insane. Damn, I had to grab a pillow to mask my screaming in pleasure. The lady asked if I was OK because she thought that I passed out for a second or two. I still compare all my orgasms to my first time, and I'm still trying to relive that particular time. I wonder where she is?

all you have to do is read my last review on Goddessjezebel.  She will travel anywhere.
