So, a friend of mine raised another concern besides a condom slip...

Hello, a few days ago which AnxiousNoMore helped me with;

While it's helpful, a friend of mine raised another concern besides the possibility of the condom slipping being the reason why she ask to another condom - there's also the possibility of a condom breakage. With this new possibility, do I need to get a check up just to be safe?

Condom breakage is really noticeable.  Pin size holes and little tears are not reality and a broken condom is a noticeable mess.  If your condom broke man, you'd know it so what if about this possibility is not realistic.  Your anxiety is working hard to keep you worried.  Try not to give into it.  (and your friend is no help here.)

Ah, I was actually referring to AnxiousNoMore's answer being helpful, not my friend's concern... but thanks for the answer... I personally didn't feel anything breakage or anything prior to the sex worker saying we need to get another condom. My initial thought is that it either slipped or she realizes that it's not encouraged to use the same condom once its removed, thus stopping after a brief intercourse (lasting few seconds) and said we need a different one. I understand my friend was concerned but it also raised some concern.

I understand.  However, it's not really a concern and that was my main point.  You'd know if the condom broke.  Adding in things that are what if's just make you ore anxious.  A condom slipping is also not a concern because only the head has to be covered. And look at it this way, you had a worker that cared.  She is trying to protect herself and wants the condom changed.  Which means she's careful.  I'd really consider moving on and letting the worry go.
