Have you ever walked in on someone receiving an enema, rectal temp, suppository etc

Have you ever accidentally walked in on someone in a vulnerable exposed situation? Example: someone receiving an enema, suppository, rectal temp, spanking etc.

What was their reaction or yours? Was it something that turned you on or was it just the opposite under the circumstances?

I always fantasized about walking in on my ex wife under one of these conditions. Sadly it never happened, however I did get to purposely witness some which was great!
