This isn't about sex. He's saying he wants his luck to stay with him the way a lady would. "You might refuse to stay/
And so the best that I can do is pray." He hopes his luck will stick with him.
"The pickings have been lush
And yet before the evening is over
You might give me the brush"
^^He's been lucky so far but by the end of the night his luck could run out. It's about gambling in Vegas. Simple. Great song.
