That's a question raised by this post on GuySpeak, which asks for the male opinion of a girl who curses frequently.
The guy's response? Cursing is kind of hot, assuming it's done at the appropriate time.
I think we've gotten to the point where cursing is rarely a relationship dealbreaker, unless it's taken to an extreme.
For example, it's kind of weird dating somebody who needlessly inserts four-letter words into a discussion about frozen burritos.
Conversely, it can also be uncomfortable to have a boyfriend with a vocabulary so pristine that you worry you'll get your mouth cleaned out with soap in the middle of the night.
Generally, I'll allow a partner one massive foul-mouthed blowup a month. It usually takes place in traffic.
Thoughts?
