i had sex about a 3 weeks ago with my ex boyfriend that just got aout of jail.and he didnt pull out so he came inside of me and since then i have a fishy smell in my vagina. there is nothing coming out of me. no discharge, nothing that is not normal. ut when i have sex. i smell like fish and is just nasty. is not that bad but you can smell it. it doesnt hurt when i urinate or when i have sex. it just the smell when i have sex.
