What Causes Bumps And Swelling In Vagina After Sexual Intercourse?

Me and my boyfriend had sex on the 10th. he used alot of lubricant. I m also allergic to latex and we used one the night before. I was getting irritation so he took it off. The 11th that morning I was extremely sore, red, and swollen. Painful to sit down walk etc. 12th blister like bumps show up and they hurt very bad. I ve never been exposed to herpes or anything of the sort. and im very scared. could this just be a bad allergic reaction im having???
