Premature Ejaculation

Hello, me and my boyfriend have been together for years. We have sex and it seems like he always seems to cum so quick or can’t hold an erection. (We are both early 20s, & experienced so age isn’t the issue)

When we first got together I thought this was going to be a problem, but there would be certain days that he wouldn’t cum so fast. Throughout the year we bought various sex toys so that he could pleasure me a little bit before he goes in.

Recently, every time we have sex it ten minutes before he cums or loses his erection. I’m sexually frustrated bc he doesn’t seem to care. I could masturbate but it doesn’t give that same pleasure.

He did also tell me he used to have an addiction to pornography; I wonder if he is still addicted to where he can’t preform like he used to.

Am I holding my standard for sexual pleasure to high? And am I wrong for being frustrated? How would I bring this us in a conversation with him?
