I've got a date today (off tinder) where we've basically agreed to meet for coffee for half an hour or so and then if we like what we see we'll go and have sex.

I'm not sure if there's anything I can do to increase my chances here since what she'll be looking at will be mostly physical, but I was wondering if there were any tips on body language etc to make her more likely to want to fuck me (since I obviously can't do anything to change my physical appearance this late in the piece).

Thanks in advance for the help guys.
