Is it normal to not get turned on?
Depends.It depends
Yes, it can be normal not to get turned on, either sometimes or more generally. Arousal varies from person to person and can shift with stress, tiredness, medications, relationships, or simply how you’re wired.
Not getting turned on every time is very common—your body doesn’t run on command, even when you like someone or want intimacy. Some people also experience little or no sexual attraction or arousal, and that can be a normal part of who they are.
If this is a new or persistent change that bothers you, or comes with other symptoms, it’s reasonable to talk with a healthcare professional. Otherwise, you don’t have to treat your level of arousal as a problem just because it differs from someone else’s.
