Hello. I had an encounter with a sex worker at a massage parlor a few weeks ago. She rubbed my back with dry hands for about 20 minutes, then proceeded with a hand job using ky oil for the ending. I didn’t see her touch herself at any point of the encounter before handling my penis, but let’s say she did and I just didn’t see it, or what if there was fluid left on the bottle from previous client, she didn’t wash her hands, etc. am I at any risk for something like let’s say Trich? I know from what I’ve read, it seems like bacterial sti’s such as gonerea and chlamidia needs to make its way up to the membrane of the penis.. which seems would be pretty much impossible in this situation. But what about Trich? From what I’ve read something like that might not need to go that far into the penis. What is just a little bit happen to get on the tip of my penis? Probably worried about nothing but appreciate any info on my situation. Thanks!
