Sexual encounter with at a gloryhole

Hello Folks,

It brings me great shame to tell you’ll that I was not able to control my sexual urge and visited one of the glory hole locations and I was serviced (blowjob) by a Trans woman, I also have a girlfriend. I did not wear a condom how likely I am to contract any STIs and STDs although there were no cuts on penis.

Any advice on further steps is appreciated.

Should I be concerned?
