Condom

Whenever my boyfriend and I use a condom, he doesn’t stay hard. He goes soft pretty fast and then the condom starts to slip off and he goes hard again but it doesn’t sit right.

But when we don’t use a condom he doesn’t go soft ????

Is there any condoms we can get that might make it stay up?

We don’t wanna not use a condom, I’m on the pill but we want that extra precaution
