boyfriend bed issues

okay now this is kinda awkward, but hey that's what this apps for. anyway, my boyfriend and I are pretty intimate, and it's great and all, but he orgasms like 20 seconds (even that's a bit generous) after I touch his dick. he's just not very good at lasting very long. and idk what would help him. I've tried telling him that masturbating before we meet up should help him with that, but honestly that just put another 10 seconds on there. any ideas? both of us are desperate 😭
