Ever have a patient have a crush on you?

I'm a nursing student and have been taking care of a male patient my age acts bashful of any health questions I ask (turns red) and also acts tad flirtaceous (thankfully nothing personal) just innocent teasing and joking around at times. He's on the cardiac floor and thankfully, I don't have to exam him in any personal areas! A girl's intuition can often tell when someone has a "crush" or whatever it is. He is not inappropriate in any way but thee is just an awkwardness at times.

Any of you experience this?
