This is the problem with my boyfriend. He's only 28 and his sex drive is not there. I feel like I am attacking him all the time and he shows no reaction to my advances. When I talked to him about it he said that he doesn't initiate things because he would be left feeling "vulnerable". I told him it wasn't fair that I be the only vulnerable one in the relationship. He seemed to understand and was more affectionate the next day, but went back to being the same way. I just don't know what to do anymore and I don't know how to bring this up to him. It's very embarrassing for me...like I'm not attractive and I know he will be defensive about this subject. How do I work through this?
