something to add-> do it slowly and smoothly.
If u straight straight ask her "can we have sex", most probably answer is "no". Try to create the environment, do something "romantic"(we guys might not able to understand and agree to this term, but one of my normal girl fren once told me that this means sky and heaven for gals).
All the best...
P.S Btw, she aint a devoted catholic rite? If it is religious matter, then think not much u can do. unless u get married soon..
