Can I get an STD?

Okay guys, I have a question. I’m paranoid beyond belief.

Last weekend I had sex with two guys, different nights. Both I know are STD free. From having sex with them, unprotected, the bacteria and all of that jazz, would I be the one to contract and develop an STD? Even though both guys are clean?

I need satisfaction that I’m okay 😩 I tried googling it but I didn’t get much with an answer.

Your help will be helpful.
