When to worry about partners porn habits?

My bf and I have a wonderful Sex life. Maybe a little too overactive sometimes, at least 3-5x on days we’re both free from work.

I’ve always known that he watches porn and he’s very open about it. I have never felt like it negatively effects our sex life or passion.

However, I’ve started to become more aware of his habit taking more time out of his day. History log showing up that he’ll login 3x a day- on days I’m working/gone! I’m annoyed as it seems to be a contributing factor effecting his productivity + motivation..

When does it become unhealthy? How do I approach him without violating his own sexuality/pleasure choices? Or make him feel bad for (being a lump on a log letting his overactive penis dictate his day?? Lol)
