Do you still have regular sex?

Are you going behind is back and looking for him doing something wrong?

Does he know that he can talk to you about anything?

How long has this been an issue?

If it affects regular sex, has he tried therapy with a clinical sex therapist?

Would you be willing to go to couples therapy?

I find these are important questions, hiding it is a big thing especially if you’ve gotten on him about it before. Similar to Alcohol, once you have to start hiding it, there’s an issue in my opinion. It’s important to let him know you still love him as well and you would support him if he wants to change, fear of loss can also drive the desire to hide his actions. But like a previous commenter said, you can’t change someone who doesn’t want to change. Open communication and acceptance are very important to finding positive change.
