condom crisis!!!!

Harmony
So unfortunately I'm allergic to latex internally so I can't use latex condoms.
And my partner just found out that when we use non latex condoms he ends up having bad hives, numbing, and stomach pains.
We're both able to abstain from sex until we figure things out of course. Since we want to continue practicing safe sex (being in our early/mid twenties were not ready for kids).
Is there anything we can do??
