I know it's cliche but try to make the girl laugh to lighten the mood...for example, if you don't know Mandarin, maybe learn a few funny words or something.
Also, many semi girls need "direction", otherwise, they will just do their thing...it's okay to be a little assertive but just respect their boundaries. Also, with most semi girls, don't expect too much on the first visit. There's usually quite a jump in service between the first visit vs the 2nd or 3rd visit...
