Assuming the girl is comfortable, nobody is too shy to talk and there is mutual attraction, it's easy to spot the moment for the kiss during a date. When you feel there is nothing to say, it's because sexual tension is high enough and you should make a move. With some girls it comes early, with others it takes more time. I myself love to say to her that we should kiss in that moment and rarely I make a move out of the blue.

Do you guys have other perceptions?
