My wife and I have discussed her taking BBC. She has said yes to it and likes the idea. She even bought a huge dildo and gets me to use it on her. She has told me I am not big enough to hit the right spot. But when I say about her actually finding a guy she gets nervous and backs off. She says she wants but thinks it would cause something between us. I have reassured her over and over that the inky thing that will change is her getting what she deserves, and that's a bigger guy. How to I get past this? If I can?
