We didn't wait until marriage, we use to have sex twice a day, nothing crazy though we never really branched out from the typical beginner stuff, and she was still never very confident or proactive, i still controlled everything and told her what to do.
I do really think she is one of those women who can take or leave it. But you are right Wakeup i do need to express what i want more often when given the opportunity. I think she'll slowly begin to figure it out.
