If you love her wait, seriously, she was through an ordeal and secondly, I'm not sure about the situation, but if this is her first time, then any girl will be nervous, if not, still she has been through alot.
Encourage her to get counselling to deal with the trauma and just be there and be supportive, but be patient it might take a while, and if you really do care and this is a serious relationship as you say it is, you will be willing to wait as long as is neccesary.
