That is normal. The penis only needs to be erect when you have sex. The penis gets the best blood flow when it is flaccid. And erection for more than 4 hours can cause permanent injury to the penis. Plus, urination is much easier when it is flaccid.

The circadian rhythm plays a role here, and so does arousal. If you are not interested in sex at the moment, you might not have an erection.
