I think the best thing you can do is just be very patient and gentle. It seems that she is not shy which is a very good thing but in case she is then just be supportive of her.
My first few times with my boyfriend he would always tease me about me being so shy to make me feel more comfortable about what we were doing and about myself
so try to do that with her if she seems a little nervous.
Oooo! Oooo! and also talk to her very sweetly. Lol not cheezy or anything just be sweet
