Title says it all . I have a feeling that my wife want a bigger dick, she never actually said that but when we have sex especially doggy she tries to position herself so i go in as deep as i can. Btw i am 7x5.5 . i asked her if my dick is big enough for her and she said its fine but i have a feeling its just something she is telling me not to hurt my feelings . Is there a way to find out if she would prefer bigger?
