I am nervous

I had a breif encounter with a transgender (about 30 mins total). We did not have anal sex, but she tried to put her penis in my anus but I stopped her as I was uncomfortable. She was using lube but no comdom and I had a cut on my anus. She was DDF. The pain went away in 2 days and the bleeding also stopped. I dont have any itching and I can pass my stool with ease. But when I took a picture of the area it was slightly red but no boils or puss or swelling. I am getting tested but I need to know if its a very serious situation.

Thank you.
