Does anyone have any insight why all Thai providers use condoms that not wrapped individually?

She most likely took it out of the packaging to save time when time to cover-up. Delay could meen loss of your erection.

Bulk from overseas???

No - Costco has a 30 or 40 pack, but they are all individually wrapped.  If the girl brings you one that is opened already it was probally already used.

Reuse would be so ignorant ...why bother even wear one.
After this thing has been in a few places who in his right mind would want these things up their ....?
I have to give them more credit than that, maybe next time I should ask.
I'm surprised no one has already asked. Am I the only one this happens to ?

I get the economy pack from Costco and they are individually wrapped.  Be safe,  watch her open it.  And if you have an unusual size bring your own!
