Help!! Is this an std?!

I have been with this guy who I lost my virginity to for 6 months!. Before I went to the doctor, I had sex with him about 10 times!. I went over the summer and she said everything looked fine and I was negative for ghonnehrea and chlamydia!. I also told her that I get a lot of clear discharge and she said that was normal!. Last month, I slept with him 2 more times!. He seems like he has been with a lot of girls but we always used condoms!. Now, a month later, Im noticing a lot of white and bright yellow discharge now!. Its also gets itchy like inside, not really on the outside!. I havent been with anyone else, did this guy give me an std!?Www@Answer-Health@Com
