Broken condom

So a month ago my boyfriend and I had protected sex but the condom broke. We used the ultra thin ones that are 50% thinner than the regular thin ones because we can get pleasure from using them instead of other ones that just feel like plastic and we don’t feel anything. What can we do to be more careful so that it won’t break this time ? We still want to use those condoms because my boyfriend and I feel pleasure from using it. I’m not on bc but we use condoms in order to be safe.
