I have a problem. Im not huge but i'm 8" long with average thickness. My wife says its to big, and becuase of that we don't have sex that often. No matter how gentle i am. She not a big girl by an sorts so guess that may have something to do with it. She won't even give head becuase she says it to big and makes her gag. Feels awful not being able to give it to her. Any suggestions would be helpful.
