How old are you by the way? If you are too young, you should not think about this but if you are pass your legal age, what you should do is to tease her first and do the foreplay, say sweet words and she will be pleased.
i'd say to just treat her with the same respect you would with a woman your age. don't let the age difference bother you. the way you have sex doesn't change very much with most age differences. as long as you can perform good she'll enjoy it.
