Question about my boyfriend busting too quick...sigh

Okay so me and my boyfriend recently had sex, and he simply can’t go wrong...it feels amazing. I just don’t want him to stop, we are just starting so I’m all excited and extremely horny....and then after LITERALLY less than a minute, he busts like hell. He told me “baby I’m going to cum...I’m going to cum right know I can’t handle it” and I’m just like “....what....” ....he cums and then he stops obviously. Deep down I’m not finished with myself, I never get to cum unless he fingers me, and I get upset because his dick can do the work. His dick is amazing ugh...and it just drives me insane, he just dosent last for shit. I already told him about it because it’s happened before. And we even agreed that he will always jack off the day before seeing each other so he lasts a bit longer ....and nope it’s the same. We could go for round 2+ bit at that point it would just make me upset. Can anyone please give me some advice lmao...I’m always making fun of him because he’s so easy but it also bothers me at the same time :/.

Edit: by making “fun” of him, I mean we *both* tease about it, he even laughs and jokes about the noises I MAKE. I don’t make fun of him in that way so please ladies chill out. I would never blame my baby for something like this sheesh...I asked for advice...nothing else🤣
