How long have you been together?
Have you set a wedding date yet?
Why dont you talk about it with her, you dont necessarily have to have "relations" before you get married. You could tell her how you feel about this, how you dont want to upset her or hurt her or push her. Let her be the one to guide YOU. It sounds like she really wants to be intimate and please you, ultimately.
You could try things to be SUPER romantic to let her know how much she means and perhaps this will shed her of her maybe old cold ways she had with her past. Arrange a night where you cook her a fabulous meal with rose pedals that lead to the table, pull out her chair, surprise her with a small special box of chocolates or earrings? Maybe these things will help her to warm up and WANT to be intimate.
Don't let it be a barrier about her past or her father...I get the impression it's not something that will be forever with her.
You could maybe tell her that you can save your "relations" for your wedding night--let it be something you both can look forward to and work towards
All the best to you!
