My boyfriends cum made me smell like death

So, um... wtf. I finally decided to let my boyfriend cum inside me. (I’m on BC.. chill) He was super excited, and I was... along for the ride. Cut to 2 days later... my vagina smells like something died, and I’m not a fan. Ok, maybe it doesn’t smell that bad, but it’s not pleasant. He’s off tomorrow and is gonna want to go again but... I might have to be closed for fumigation
