touching invokes a more intimate relationship between two people,it could be the difference between her remembering you and her remembering 'that guy at the bar'
In a study conducted by Allan and Barbara Pease, they set up an experiment in which hey would leave a 2 dollar coin in a phone booth, and after the person who saw it and took it walked away, they would go up to them and in 10 cases, ask the person if they'd seen the coin, and in another 10 they touched their arm and asked. Results showed that it was something of a 25% return of the coin boost, as the person saw the person in a more intimate manner and felt connected to them in a way.
So touching is good, but not too much.
