Help me change my impatient thinking

My boyfriend and I have been together for awhile and our physical chemistry can be REALLY strong. We communicate during sex, we talk about how we can improve but there’s one thing really bothering me. My boyfriend has trouble focusing from his ADHD. Something always “ruins the moment” for me. He can’t control it and it’s totally okay but it just makes it harder to enjoy myself if he’s blurting things out when he isn’t focused. My man is really good in bed but it’s just that one thing that makes it a little difficult to get in the mood. He shouldn’t feel bad for something he can’t control so how do I be more patient with the situation?
