Hello. I recently had sex and my partner ejaculated inside of me. Pregnancy is not a concern, I am on Nuvaring. However, I left the semen inside me and if eventually started to drip out. After a while of walking around, I noticed my underwear was wet from having the semen come out of me and onto the panties. After two hours of walking with semen soaked undergarmets, the creases by my groin area between my thighs are red and burn, swollen and it is difficult to walk.What caused this ? How can I fix it?
