What Causes Bad Odor In The Vagina After An Intercourse?

Hi... i've had sex a few times this week and each time my bf broke in me. My vagina never smells like rotten eggs. it doesnt sting when i pee.. when i shower the outside smells okay but when i put my finger inside the hole it smells like rotten eggs.. and here 2 days later it still smells and i've been showering. But can haveing sex like 4 or five times a week and your partner is breaking in you make my vagina stink and how long will it last for? Or do i have a n infection which i hope i don't! thanks.
