I am a 17 year old healthy male, I have only been sexual active with my last girlfriend about 3 to 4 months ago. I havn't had any signs or symptoms of an STD besides I had a UTI about 3 weeks ago that lasted only a few days. Now since it's been 3 to 4 months, i still wonder if its possible she gave me a STD and my body cleared it? My main question is: how long after you come in contact with a person that has an STD, will you see the Signs or symptoms? Another reason i ask is because, a few people have told me that she has an STD, but i havent seen anything so i dont know. Please help me if you know anything, thanks!
