Hi doctors. About 1 night ago I met up with a trans girl. We made out vigorously and she spit into my mouth numerous times. While making out I grabbed her ass and spread open her asscheeks. She then sat naked on my face and rubbed her ass all over it. I didn’t open my mouth or lick it. Eventually she jerked herself off and came on her hands and then proceeded to jerk me off. I actually have some chaffing on my dick after going on a long run so there is an open cut on my penis. I’m not sure if she had cum on her hand when she jerked me off. We didn’t do oral or any sex and was wondering if I am at risk for any STDs from this scenario. Is tested warranted after this? Thank you

Welcome to the Forum.  Thanks for your questions.  I'll be glad to comment.  Despite the variety of activities you took part in, as well as the vigor of the encounter, this was a no risk encounter.  The presence of chaffing on your penis dose not change this  I would not be worried in the least and see no need for testing.  ---

Thanks so much For your answer. So it’s safe to say I can go back to sex with my girlfriend without worrying infecting her with anything?

Yes, I would be comfortable having unprotected sex with my regular partner in your situation.  EWH---
