So, um, if you're cool with her wish not to have sex at the moment while she decides what's right for her spiritually - then what is your first question?
With regard to your second question, about her self-consciousness during oral sex, you might find this thread - http://www.scarleteen.com/forum/Forum2/HTML/002192.html - illuminating about some of the anxieties people may have about oral sex.
But really, the person most likely to know what would make her more comfortable is her, so your best bet is to ask.
And if it turns out that she's uncomfortable with oral sex because she feels that any sort of sex is wrong for her spiritually, or she just doesn't want it, for whatever reason, then obviously you have to respect that.
Ultimately, if it turns out that her spiritual beliefs are totally incompatible with what you want to be doing sexually, then your sexual relationship may not have much of a future.
Sometimes people's lives, choices and preferences mean that they are not going to be sexually compatible, and there's not much we can do about that.
