STD???

So in my first semester of college I had unprotected sex with a football player it was the worst sex of my life. He said he was clean and I had absolutely no symptoms of an STD after so I didn’t go get checked. A couple of months later I’m in a loving relationship with this sweet boy and he recently started to have penile discharge. I had a UTI a couple of weeks ago but it went away about 2 days later. I haven’t really had symptoms since. We don’t use condoms because I’m on birth control and we both thought we were clean....But I’m worried I gave him an STD. He’s supposed to go get checked sometime this week. He only has penile discharge and his penis is starting to smell bad there’s no itching or burning and he has no pain in his testicles. I’m freaking out. What should I do? Do you think I have an STD? I know for women some of them are asymptotic.
