TTC w/ Allergies

TTC for the first time, and have never baby danced unprotected before. Done it 5 times since Memorial Day weekend and each time he finishes I HURT. Not when I pee, all of that is fine. 👌🏾 It’s just after we’re done my girlie goods literally feel swollen, hot, sore, and it takes a couple of hours to put out the “Australian brush fire” as I’ve now dubbed it. This never happened with condoms, except once when we tried some new his & hers type. Which makes me now terrified that I might be suffering from an allergic reaction to my husband’s baby making protein. 🤦🏽‍♀️😨 What do you think?
