Upcoming wedding and counseling...

I'm a man, so I don't even know if I'm allowed to post here. I'd just like some honest responses and I feel like that is what I will get here, unlike asking at some other sites.

My fiance and I are getting married later this year. We want to meet with the preacher who is going to be performing our ceremony for pre-marital counseling, but my fiance is worried that the preacher will question my Christianity. My fiance knows that I grew up in a Baptist church and that I have accepted Lord Jesus Christ as my savior and that I have been baptized. She has been very active in the church and has attended a Christian college. What would make her feel this way about my religion and my personal relationship with Jesus? I have talked with her about it and she said that she feels I don't take my religion seriously. When did religion become a competition?

I'm confused and don't want to embarass myself or my fiance in front of the preacher. What advice can you give me to ensure that the counseling sessions go well? And what do women expect from their husbands in terms of including God in their marriage?
