Indeed...
Infact, recognising these windows of opertunity is CRUCIAL to your game. You can't just force your way into a womans heart. You have to watch for the small frames of time in which she opens her heart and you can slowly move in there.
There are windows for everything going from the first encounter to the first kiss to sexually charging the conversation...
The clue is to look for signals, things she says, her body language etc. If you want to kiss a woman and make it seem like it 'just happened'. Taking steps at the right time is very important, if not it makes you seem clumbsy, perhaps you will come on to strong and scare her off.
Charging in isn't always the best approach. It's better to charge in after a minimal amount of confirmation!
And yeah ofcourse it's an individual thing. Women ARE individuals after all! Some women will be ready for a kiss very fast, or for a shag. Others won't. Being alienated in an interaction because you're thinking tomuch of your gameplan or strategy is the perfect way to kill any chemistry. Be THERE, at that time and place, tur up the fire, see how she reacts, have your next move depend on her reaction.
ex. You are looking for a window to kiss her. It doesn't come and you decide to charge in anyways, she might let you but you are overwhelming her... if you move the conversation in a sexual direction at this point you are more than likely going to scare her off!
