We had sex a week back and I was fine after the act. But a week later, I got the odor of semen from the vagina. I did have mild itching. I then used lactic acid lotion (vaginal wash) and finally got rid of it. But again since today I'm getting the same odor of semen with mild itching.
I do not understand why the smell comes after many days after sex. Moreover I was not having any problem during/after sex.
