LOL. I have two suggestions to share:
1. Ask her what she likes. If it is something you like too, then
you have something that is of interest to her to chat about with
her. If it is something you are not familiar with, then ask her to
tell you about it and you PRETEND to be interested. Add in a few
"Woah!", "Cool~", "Really?" once every 2 seconds.
2. Just chit-chat about anything but make sure you drop information
about yourself to her. Let her know how muscular you are, how nice
your hair is, how firm your ass is, and probably how huge your xxx
is.
