Most of my "porn buddies" as you put it, are people in the porn "business" and have the ability to act in a socially acceptable manor and conduct themselves appropriately even in front of my 7and 9 year old daughters... So, the answer is yes.
If they can't act appropriately in that situation, likely not my buddy, friend, or associate... but that's not to say there are people in this biz that I chose not to be around or associate with, and actually it's not just limited to this biz...
Time and place for everything, I can party with the best of 'em, but also know when not to as well...
