I had sex 3 days ago. earlier today, the inside of my vagina was itching. it doesn't itch that bad. i took a shower and washed down there real good.

?infection: If the itching goes away you should not worry. Vaginal itching can occur for many reasons. If you used a condom during sex then it may just be due to irritation or allergy. Other common causes of vaginal itching include infections with yeast or bacteria and a STD known as trichomoniasis. If your itching continues you should be checked for these infections.
