My girlfriend said she doesn’t like words that are too vulgar. Now when I send her a text message, I have to check it after I type it...

Did she say no when I kissed her for the first time, but she still kissed her, and she felt very happy afterwards. Girls always don't mean what they say. Just say it from the bottom of your heart, as long as you say it sincerely, she will know it's true no matter how stupid it is (as long as she's not stupid). It may sound disgusting if you don't mean it, but you can consider it from her perspective.
