While I do listen to him if he has an objection for some reason, I was/is my choice.
It was never to the point of me listening to him and not letting my boytoy cum inside me. We would have sorted this out before I left. He can ask me not to go. He has rarely done that. Once in a while, he just does not feel right about what is happening. It's very obvious when he has an issue. I just simply don't go and stay with him.
If I'm playing then everyone is tested and clean. So, it's expected he's going to cum inside me. The "fun" for use once in a while was if I would put my diaphragm in. He'd ask and sometimes I'd go, "That will be a game time decision" and make him sweat it out until I get home.
We have our fun together and apart.
