Until quite recently I used to struggle with kino escalation, which as any aspiring PUA knows, has a devastating effect on your game. Eventually I realised that as long as you start off small (e.g. playfully elbowing her) and increase slowly then you'll never go wrong. However, I do realise that it seems unnatural to a lot of people, but if you can't get a girl comfortable enough to let you play with her hands or let you link arms with her then why would you think she would be comfortable kissing you, right?
So, the 'Trust Test' is a great way to OVERTLY get some kino going. You don't have to worry about her thinking 'why is guy touching me, it's freaking me out', because she will know in advance that you're going to hold her hands and you'll be talking about it all the way through. It's genius. I've only just found this gem so still have yet to try this out infield but will do so with the first girl I speak to tomorrow and report back.
Check out the link at the bottom of this post. I strongly suggest watching the whole video if you're new to the game, however if you already consider yourself a PUA then you will be hearing a lot of the same information you have already heard, so just skip to 30:00.
