I have had several sexual partners since I became sexually active in high school. I had never experienced discomfort during sex, but recently I noticed that when I have sex with my current boyfriend, wherever my skin comes into contact with his semen, it turns red and becomes irritated. After intercourse, my vagina is red and puffy too, not just my skin. We can’t use condoms because I have a severe latex allergy, but I am on birth control, so we aren’t worried about unplanned pregnancy. Could I be allergic to his semen too?
