Is this unhealthy or an addiction?

I just found out my boyfriend masturbates 10+ times a day. He also spends hours watching porn everyday, even at work he is watching porn and masturbating. He is pretty much unable to preform with me and always has been but he told me that he had an ED. He said he has tried to quit but has been unable to stop for more than a couple hours and then he is right back to doing these things. I’m not trying to be insecure or whatever. I have strong feeling on no porn in my relationships but have always found masturbation normal. But for hours out of the day? Is this an addiction? Does he need to seek help? Is this normal for a man?
