ok this may sound strange, but I actually asked my wife to talk to me more during sex. I have low self image and sometime performance insecurities. I am not asking her to tell me about her day or about the book she is reading. I want her to express how she is feeling at that moment, how I make her feel. I guess I am looking for reassurance that what I am doing is good and right. I want to know that she enjoys sex with me and that it is pleasurable to her as well. I want my wife to tell me when she is close to and when she reaches maximum arousal. For me there is no greater self image booster than knowing I took her to the stars. I dont know about your situation, but maybe she wants to be reassured she is pleasing you. Being told what an awsome lover you are during sex can be very stimulating.
