You should always atleast get to the point that you are french kissing the girl on the first date.
Why? Because it shows intent. You need to show to the girl that you are not friend zone material.
If you are not trying to create sexual chemistry this can happen really easy, The girl will postion you on her friends zones and If she is you are probably wasting your time with her, just because this is not what you are looking for.
They way to create that sexual cheimstry are as follows:
1 . right on the start of the date when you meet each other and say hello go for the hug and kisses on the cheek .
This will establish that you are a warm person who is not afraid of touch and it is a social convention to do that, almost no girl will turn you down with this.
2 . During the date you should look at her eyes while she talks and while you talk but not constantly. You should look away for time to time or else it will be creepy. Plus when you look away you will probably see thing that you can comment about and this can revive a dead conversation.
3 . While you are talking dont afraid to casually touch her on the hand like you would do to a good friend. Any kind of friendly touch is good - pat on the shoulder, touching her finger to check her ring and etc..This will continue set the tone that you are a worm person and she will start to feel comfortable around you as long as you dont exaggerate . Everying needs to feel friendly untill this point.
4 .This is really important! Dont stay too long at the resturant/ coffee place / whatever. After you've done eating or drinking and the conversation seems to fall out of steem (steem :)) immediately offer to leave. You dont want her to get tired and want to end the date out of boredom. When you both leaving the place you should try to engage a hand to hand grab and walk like this:
You dont need to ask just go for her hand and see how she respond. Most of the girls will approve if you had a good flowing conversation before.
This move will immediately elevate the sexual tension on the date which is what you want and is a must in order to get to a french kiss.
5 . While you are walking try to find a nice place for both of you to sit like at a bench in the park or something like that. Continue to talk and continue looking in her eyes but this time you can start complimenting her on how beautiful her eyes looks or her smile (you need to focus on her face) dont be afraid of moments of silence while you both looking to each other face. this is good. allow her to giggle and giggle yourself a little.
6 . Now go for the kiss! 95% that she will approve if you done everything right until now.
