Recently, during a phone conversation with my boyfriend, he told me that he turned the volume up on his phone. Soon after, he began to masturbate, while he was talking. I am well aware of phone sex, but the conversation never came up. I had no idea what to say to him. It was very loud and there was no mistaking those sounds. Should I confront him or let it go? Do many men find this satisfying? He complains about not being able to sleep. Could this have something to do with this?
