If she is in the medical field, half the work is already done for you. Bring up the human anatomy as often as possible. Talk about how kids made fun of you for your large hands, feet, and ears, even if its not true.
Try to work words like 'donkey' and 'enormous' into the conversation whenever possible.
You can also fake a choking fit, knowing that she'll perform the heimlic, drawing in physical contact. It wouldnt be the worst thing in the world to be in full arousal at this point, too, giving her a glimpse into her future.
I guarantee you she'll be thinking about a second date after this.
