Did my first time... Have a few questions

Wasn't as great as I thought, but meh.Anyways what's been bothering me is that I'm worried about STDs. My partner didn't have a condom so I avoided bottoming. I'm clean and I topped him, and I also gave him a bj, where I think I swallowed some of his precum (not cum).Am I at risk? I don't know if he's clean or not, but the fact that he didnt have a condom worried me.
