sensitiveso

My wife is very traditional in the bedroom. It takes a lot of coaxing (sometimes some alcohol) to open her up to having fun. I like to explore her body for her G-spot. She becomes very sensitive very quickly with any type of vaginal foreplay, whether it be gentle oral, using my fingers, etc. I've read other threads about women who attempt to ejaculate using various methods - I wish my wife would be so willing. Otherwise, we have a great marriage so I don't think the relationship is the problem. How can I get her to be more adventurous (and comfortable) in the bedroom?
