Allergic to Latex?

So my go to and preferred brand of condoms is Skyn. They were the first ones I ever used but not cause of a latex allergy. (I had just heard great reviews about them.) But about a week ago my doctor’s office gave me free condoms and the brand was Trojan. I never used Trojan but I gave it a shot. They were actually the condoms we used for anal and I didn’t have any problems. But when we did vaginal my vagina went numb and started itching. But after sex the itchiness went away. Is there a possibility just my vagina is allergic? Or is it just a minor allergy I can feel more in my vagina?
