Okay so a few days ago I had sex for the first time. At first it was unprotected but then he put a condom on. Since that day I have been getting yellow discharges... Um it smells musty not so foul though. I looked it up online And it said that this discharge may be a cause of an STD. I don t have any symptoms like itching or pain when I urinate. I checked today and the discharge was white/clearish. I really don t know what it means should I go get myself checked? Or what may be the cause of this please help! And thank you.
