best condoms?

so im on bc but we still also use condoms but the problem is, he has a hard time finishing with condoms. i mean at first when we first started having sex, he used to cum fine but now its getting harder and i have to give him a blowjob after for him to cum. i mean i would go bare if i didnt have the worst anxiety ever about my bc failing so that isnt a option. right now we use magnum ultra thin they are perfect and we never have a problem with it only that one thing. any suggestions on other brands of condoms?
