UTIs are exactly what their name describes. and infection
in your urinary tract
. its not in your vagina, however, ive always been told not to have sex while you have one because sex could be the cause of it. and its best to make sure its all better before introducing even more bacteria. Ive never heard of it being contagious, and dont think that it is, but ask your doctor. and ive also never had a cream to use, so im not sure what thats for.
