i (22f) had a one night stand with a guy like three days ago and the condom kept falling off and he did end up finishing inside me (i have an iud) but ever since then my coochie has smelled a little like old cum every time i go to the bathroom? i thought it might be BV but it doesn’t really smell fishy- just like stale cum. it isn’t itchy or inflamed and i haven’t had any weird discharge. i have wiped it off and washed with just water (and i peed right after) and a very gentle unscented soap but it still smells a little weird? i know i should have been more careful with this guy but does anyone know what it could be/how to fix it?
