Comparing myself to the other woman

I'm an LDS lady who's getting married to a returned missionary, he's amazing and everything is amazing. Except for the fact that he's not a virgin. I don't know how I'm not going to compare myself to her. I don't have anyone or anything to compare him to and I worry that I won't be as good as she was. I've communicated with him a bit on this and he keeps validating me and telling me I should never worry and he regrets it and it was bad because it was both their first time and blah blah blah, but as a person. I wanted to share this special moment with my husband. any advice?
