You really should go see a doc and get checked out for a uti. It's very common to have this happen after sex. Make sure to void before and after sex next time, this will help decrease the likely hood of developing an infection. Don't wait to see a doc. The infection will not go away on it's own and you can end up damaging your bladder and/or kidney if you don't take care of it.
