Wanting to cum😩

I've been with my husband for over 5 years and I've never had an orgasm with him. He definitely tries and it feels good most of the time. He's a very large man and I'm a very small lady so some positions are hard to take tbh lol... I feel like if he were to make me cum it would take like an hour or more for me to get there and that might make him feel discouraged. He already feels kinda weird when I ask him for round two because he asks "I didn't do it for you the first time?" Props to him though bc although he usually goes soft after he cums he still offers to go longer just for me lol. He talks about eating me out and stuff but I wish it was easier than that to get off.... Do y'all have any tips to orgasm quicker or at all??? I mainly just can't stay focused while doing it and when we first started having sex years ago (I was a virgin) it just hurt every time and one time almost sent me to the hospital bc he went too deep I guess, we use lube when we need it and it goes fine I just can't orgasm even with some foreplay and even with clitoral stimulus while he's in me.. we've come a long way though because now it feels good 97% of the time amazing.... I just want to orgasm y'all
