water as lube

i thought just water would be a good idea to use because i started to dry up and now i'm reading you shouldn't use JUST water, if anything you should use water based lubes. apparently water can like... break down the condom or something? we used the water like 5 times or so in one go and used a condom.. i didn't get to check the condom for tears or anything after. now i'm nervous. i'm on birth control.
