One of my close girl friends asked me about this as she had wanted to try using a vibrator but her husband was not keen on the idea.
My husband has known for a long time that I have a vibrator (various over the years), it's no secret, but I don't usually tell him when or if I have used it. He is fine knowing I use on but doesn't need to know how often or when.
Does anyone specifically tell their partner or do you just keep this to yourself?
