I love it when people break down media-created sexual constructs. Dr. Kristen Mark is absolutely right in her article that all we ever see in films or read in books is that great sex leads to cumming at the same time. But in reality, how many of us get to experience that?
In reality, it is a rare, rare instance. Certainly, love it if you get it, but try not to get hung up on it.
If it seems that you’re partner is going to get there first, take the moment to watch their face and body and you help them reach their peak. Look at all of their motions and reactions as pleasure sweeps over their body. That can be satisfaction enough!
