As with most things communication can help immensely. It doesn't have to be a full on pre match discussion, but I find when Mr LNT goes down on me, which I love btw, I can guide him with my hands, or by a small movement of my hips or verbally.
I am wondering if maybe you could consider a blindfold, could take away any awkward 'where shall I look' feelings.
+1 this! No need to be awkward around each other - you're both learning for your benefit ;)
