How can I make my partner last longer

I’ve been w. my current boyfriend for 6m going on 7, and he’s been the best thing that’s ever happened to me! I like to think that my G. grandma sent him to me they’re both Cancers lol I’m a Sag . I love this man deeply but the sex isn’t the best and we’ve discussed this and tried different solutions.. let’s just say not all of them worked for long .. he blames himself for his dick being small , I blame him for cumming too quickly🤦🏾‍♀️.. the point is how can I make this man last long !!! so I can orgasm as well. I do everything his way so he can let a few loads out and the only time I orgasm is if he eats me🙄 that’s if he’s in the mood to eat me up like skittles ... but the feeling of a orgasm while a dick is inside of you just what I need 🤤😫 .
