I love the start... the excitement of the new possibility, the getting to know each other and how the exhiliration takes off the further and deeper you get to know each other all building to the moment when you finally consummate the relationship. It seems to fill you with a zest and energy, you wake up and it's a beautiful day and you want to get out of bed.
This is of course if it works for the both of you, otherwise you fall flat on your face
...though after the initial fall, that can be fun too.
