I Had Unprotected Sex With A Tranny, I Inserted My

I had unprotected sex with a tranny, I inserted my penis inside her and ejaculated inside. The whole thing lasted no more than 3/4 minutes and I cleaned up afterwards. Unfortunately the guilt and regret came afterwards, she assures me that she is clean, was tested 2 months ago and the last time she had unprotected anal was more than a year and a half ago. while looking at that area, her anus and surrounding area looked very clean, shaven and no bumps, scars or lesions at all. I know that doesn't mean she is clean, but she also used lotion and my penis slipped in and out very easily. She also douched earlier before i met with her. What are my risks please?
