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.
I'm loyal to my thoughts, to my friends. This is what I really like the best. Loyalty. Sounds goody-goody. Maybe that's not the one you wanted.
