It varies in my (limited) experience
[QUOTE=Admin2;2354371]I did a duo last year where no condom change was required. The ladies were INTIMATELY familiar with each others conchitas. My changing, or not changing, a condom did not expose them to anything more than they already had been by burying their faces in each other crotches.
Sadly they declined my offer of matrimony.
Sigh.
A2.[/QUOTE]I have only partaken of 3 duos, though I plan to do it more often as funds and circumstances allow. Changes were required once, but were not required the other two times. All 3 sessions were completely different ladies, and each time there was plenty of g / g pussy eating, so I don't think any of them were concerned about catching something from the other girl. Changing was not an issue, as far as I was concerned, and the times it wasn't required, I asked first.
A2, if I could find them at the Argentine rates, I would do my best to catch with you on the numbers. LOL.
