I, for example, love to give and receive a really good massage as part of my experience.

However, it's important to note that it's not so much the what, but the how, that really makes an experience memorable.

Unfortunately, words fail me when trying to give dimensions to this, but I know it when I see it.

I think that mutual chemestry has a lot to do with it.

meeting a lady with whom you have chemistry is what makes a wonderful experience.

Chemistry is to an extent "made"

Be upbeat, friendly, confident, outgoing, giving, complimentary, sensual, appreciative

and the odds are you will experience good chemistry -

after that, simply relate sexually in a natural fasion, and whatever happens will likely please you, and form a wonderful memory

This os of course ASSUMING that you have done your homework in advance and chosen a lady whose appearance, rate, and normative services appeal to you....

A great experience is the result of two people letting go and allowing themselves to get into each other.  There is no real formula. The acronyms and the order in which they occur are both irrelevant if the chemistry is there.

For me it's not the acts at all. The warmth and giving of the

lady I am with are what turns me on.

It's the passion and intimacy that makes it special.

That's what sticks in my mind.

For me it's more if we both click. Looks help but to get that "it" factor aka have chemistry.

Being wanted, desired and appreciated during an encounter.  
Satisfaction from pleasing the woman.  
Evoking all the senses of the body to make it a whole body experience.  
No unpleasant distracters such as bad breath or bad body scents.  
Some intimate time before departure to share a little of our human self.
