My boyfriend and I used a latex condom the other day which had spermicide on it. Within the next few days I started to feel a burn when I peed and a severe pain. I have to pee frequently and often nothing really comes out but it burns a lot and is painful. I'm not sure if it is due to the condom. I have thought it is either a uti or a latex allergy but they seem to have basically the same symptoms; however, it also slightly burns when I'm not doing anything like just sitting down or walking. Help!
