So my bf and i had sex and im on the last day of my period. we used a condom and before when we had used them, we had gotten trojan ribbed and it cause burning, so we asumed it was the ribbing. we used regular trojan this time and when we were done my vagina was burning like crazy and it looks like its turned inside outside out or severly swollen. could this be a latex allergy? Im almost 18
