And just to add: sure you go without extra lube.
But make sure you try it *with* extra lube first.
Without extra lube, it not only won't be as good for the condom (adding extra lube helps prevent breakage), it also won't feel as good for you and your partners!
From experience I can attest that condoms feel a zillion times better when you add lube - a drop on the inside for your partner, a more generous amount on you and the outside.
Give it a try, celery. It really is better with than without.
