My wife and I are trying to bring the spark back into the bedroom and tried some more risqué stuff that we haven't done before.
During it I said something and she started crying and said red flag. I immediately stopped everything and comforted her while she cried. We were both laying there naked while she was in my arms and I was apologizing. It last maybe five minutes.
But once it was over we consulted each other, debating on whether to continue or take a break and come back later. We decided to continue and it was the most amazing sex we have ever had since we've been together.
TL;DR wife and I hit a red flag during sex. After consulting with each other it was the best sex we've ever had
