I have two stories to share.
One - a couple of years ago, I made an appointment for someone I'd seen a couple of times and it was just for oral. When I arrived I thought she looked paler than usual, but didnt' think anything further. Part way into oral, all of sudden she stopped and I realized she'd passed out. (I'd like to think she fainted at the size of my dick, but that's wishful thinking).
Didn't know what to do - thought about calling 911, but she seemed to be breathing okay. Eventually got a damp face cloth for her and she came to. Turned out she was fighting off a flu bug and was totally exhausted. Don't know why she even accepted an appointment and while she offerred to finish the deed, by this time I'd lost all enthusiasm.
The second was more nerve-wracking. Quite some time ago, but booked an appointment with an SP who I had also seen a few times and just for oral. In the shower, when I hear knocking on the door and someone calling "It's the police." Turns out the SP had friend over earlier (not a pimp) who was known to the police and he'd stabbed someone in the area and they were looking for him.
Police hear me in the shower and ask who's there. She states her boyfriend, but police are skeptical and ask me to come out. If there had been a bathroom window, I would have tried to escape but no luck. Got myself toweled off, came out and said hello. They didn't ask for any ID and since I knew the SP a little, it was obvious that we weren't total strangers - though I was obviously a lot older and I think they suspected the situation.
However, they weren't vice so not interested in that. We ended up talking for about 20 minutes before they left.
While we both laughed about it afterwards, it could have turned out a lot worse. Plus afterwards, we ended up in a very PSE encounter probably just to release all our stress! I haven't seen her since (and won't reveal her identity) and she's now living in another city.
However, this is one of the reasons, I now probably prefer to have just one special SP in my life.
