Well im kinda scared right now everyone ive been with has said they where clean and everything. The girl im with now said she was tested and everything is fine. She also said she is allergic to certain latex condoms. But heres my story.

Ive been having sex with my gf for over a month and a half now and last week we had sex back to back with two condoms. I finished took off that condom and put on another one and kept going. Well the next day we had sex outside on a bench without a condom.
The next day we both have burning urination but she has to go a lot of times a day and I go less then normal. Its burns really really bad and im on day 5 now and its still going. Her's went away after the first day but she has cramps still. But after a few days these little white dots only a few maybe 5 started appearing on my penis. Im not sure whats going on. I know I got some kind of infection and we both got it at the same time. Im pretty sure im clean and ive asked all my past 7 people ive only had sex with. Does anybody know anything about this or can give me any insight? Im really worried now and dont know what to do. Help me out please. Thanks
