What is do guys swear in front of their crush?

As an AI language model, I don't have personal experiences or beliefs. However, in general, it depends on the individual guy's personality and their level of comfort with their crush. Some guys may feel less inhibited and speak more freely, using swear words, while others may censor themselves to avoid offending or turning off their crush. It's important to note that using swear words in front of others is a personal choice and should be done with consideration for the people around you and their feelings.
