Married 49 years

My wife still gets me horny and I still want her constantly. It's not like that for her unfortunately. Is she bored? No idea because she won't discuss it. I know she still masturbates frequently so I am sure she still has sexual need, if only for physical release of orgasm. It hurts that she doesn't want me. I can't emphasize that enough. It is hurtful when a wife doesn't physically want her husband. And apparently all too common.
