Is it ok to swear a lot?

It depends on how you look at it. I'm very much the same, haven picked up on swearing way too much from the year I was in the military thanks to my superiors. I need to cut down for sure.
Also depends on things like:
Your age
Who do you curse the most around?
Do you have kids or are there children commonly in your presence?
Do you use it at someone inappropriately?
