There have been a number of surveys of married women where a significant proportion of them answered wrongly about their husbands' circuncision status. The fact is that unless they know what to look for a lot of people have difficulty telling the diference when a penis is erect. I don't understand this myself but it's true. In Europe the vast majority of males have their foreskins and there is no issue about oral sex there. Even in the US, which is the last western country to still circumcise over half it's newborn males, foreskins are now much more common and accepted as normal. I have seen plenty of similar questions to yours on these boards answered by US girls who love giving oral sex to their partners.
It's unlikely your sexual partner will see the papules either unless you are having sex under really strong lighting. I have papules myself and I have been circumcised since birth. No sexual partner including my wife has ever even noticed them. They are normal and are connected to clusters of nerves so they enhance sensation. Since they are not a disease and therefore not contagious, there is no need to point them out. Some young men on this board have become obsessed about them, worried how women will react to them. As far as I know not one of them has actually shown their penis to a girl and got a negative reaction. If a girl askes about them, the simple, truthful answer is that they are normal and not a disease.
Hope that helps,
