My DH has recently started asking me to try deep throat when we do oral sex. He says it's something he's often thought about but never felt comfortable asking for before now. It has caught me by surprise and thrown me a bit tbh because I thought we were both satisfied with our sex life. I don't have a long held unsatisfied desire, for instance. Sex is a private thing and I would feel uncomfortable asking friends IRL if they've had similar unexpected requests at our age. We're both 60.
