Mate - here are my personal rules (many years punting globally):
1. make time in your schedule. if you rush, or feel pressured, whatever your nuts are saying, it will be less relaxed and more likely to be disappointing.
2. yes, tell her what you want. be cool if it's not her thing.
3. tell her how beautiful / wonderful / sexy she is. be polite and groomed. direct, simple compliments never hurt.
4. recognize it's going to be ace sometimes, and a fucking waste of time and money other times. as the yanks say, "it's a crap shoot".
good luck
