Help!! Boyfriend can’t last

My boyfriend and I have very recently just made things official, and have been sleeping with each other for about 2 months now. We were really good friends for about 4 months prior to either of us growing and admitting feelings. Ever since we’ve been together, unless he’s super drunk he literally cannot last longer than about 10 seconds. Some nights he doesn’t even try at all or give me a kiss good night he goes straight to sleep. It’s getting to the point where I’m starting to feel angry cause I guess I’m sexually frustrated! Is this wrong of me? And can a stone give me any tips to help him?
