Latex allergy?

Avani • 20 // San Francisco

Me and my SO don't use condoms anymore (I have the arm implant) but at the beginning of our relationship we did. We typically used Trojan. Near the end of intercourse or right after, I felt this burning sensation. I didn't feel it every time we used a condom but every time I did feel it, it was when we did use one. My question is if that's maybe a sign that I'm allergic to the latex? Or maybe another issue?
