Bad word

I never meant to say bad words and swears as I was growing up. I never use most of them at all, except for the word, "stupid". The word I said earlier today, I'm not going to say it, but, I'll spell it. I used it today. It's "cum". I don't want to say that word anymore, I don't want to know what that word means. I go to church and part of me doesn't feel comfortable using that word as well as other swears too and another bad word I don't use besides "stupid". Am I weird or what?
