The ts had a comdom on & didn't even cum anyway- you're fine. Like another said, your biggest risk is getting something from the owo- a ladyboy in Thailand gave me owo once (i was there with my wife....) & a day later it was singing when i peed. This got worse & worse, until puss was coming out....i told Mrs i had a urine infection. Went to pharmacy alone, & before i'd even said the problem to the pharmacist, she gave me some pills (amoxycilin i think?) told me to complete the course. Just a day later i was feeling much better. Still don't know what std i picked up? It was a good blow job though....
