In my opinion, there is a certain kind of magic between two people when they play the first time. This is especially true if they share a lot of common interests and/or connect well. These first-off meetings make real impressions on people and set the entire tone for a visit or even a relationship.
Thats why it is important to make as much use of it as possible -- In my case I had someone who had planned out several scenes in advance to my visit, and a VERY interesting airport pick up and first night It put my head in the right place and it was definitely and experience i will remember.
If it's someone you are meeting for the first time and you think that you are going to connect well, make sure you have shared a lot of thoughts/fantasies with each other. A good friend of mine likes to do this long in advance so you have time to forget what you asked for (It does make for an interesting time later).
I think some of the contributors to this factor are:
- Apprehension about the Person (Yes, this can and does make some people sexually charged)
- Fear of the Unknown
- Memory (Maybe you dont remember all you've discussed)
- Anticipation (Of what the person may be capable of, or how hard/strict)
This is not a comprehensive list, just random bits.
I'm not sure what else to add here, just thinking out loud this morning :)
