When we try talking about it, she gets very defensive and denies doing it or needing it. We’re both over 50, make good money, have a good, communicative relationship (except about sex) and love each other. I just don’t understand why she doesn’t want me as much as she wants her vibrator. We have used it together and, when we do, the sex is great, but I desire more sex than she does. But, when she does, it seems there is nothing left for me. My wife regularly uses her vibrator when I’m not around.
