Approaching a girl and getting her attention is not a problem for me ,problem is escalating sexually, I just don't know how to go into that mode and escalate, in the end close.

Standard tricks I use is 'unintentional' touching, maybe grabbing her hand and leading her somewhere away or to the bar for drinks and checking out her necklace or rings and complimenting it. These 3 bring me further but still I just can't freaking put myself in the mindset to realise does she want to be kissed here, right now, or by me even?

Thanks.
