Why is failure the first thing I think of when I find myself in this sort of situation? Why can't I just enjoy myself? But if you have to ask the question, then you know you're lost: self-consciousness is a man's worst enemy. Already I'm wondering whether she's as aware of my erection as I am.
If you're walking with your lady on the sidewalk, I still like to see a man walking street-side, to protect the lady from traffic. I grew up with that, and I hate to see something like that get lost. I still like to see that a man opens the door. I like those touches of chivalry that are fast disappearing.
